Abstract In what follows I analyse how two Neapolitan songs enhance viewer perspective of the personalities of the protagonists of the classic film of Italian neorealism, Ladri di biciclette (Bicycle Thieves) by De Sica (1948), Antonio Ricci and his son Bruno. The first, 'Ciccio formaggio', casts into relief Antonio's masculine self-image, particularly his reaction to the impact of unemployment on his traditional role of pater familias and to the possibility of public humiliation, should he fail to retrieve his bicycle. While 'Ciccio' sheds light on the tension in the marital relationship, 'Tammurriata' allows the viewer to consider Bruno's marginalization within a self-perpetuating cycle of poverty, thus shifting focus, at least partially, from the father to the long-term effects on the son (for which Antonio feels shame born of inadequacy).

Streszczenie:

Being one of the most influential cinematic movements in film history, Italian neorealism has not been very easy to define. Although one can easily recognize a neorealist film, not all neorealist films share the exact same characteristics. In this paper, four films that have often been labeled as neorealist will be discussed in light of their makers’ views on neorealism and the general characteristics of neorealism as a movement. These films are Roberto Rossellini’s Germania anno zero (1948), Vittorio De Sica’s Ladri di biciclette (1948) and Umberto D. (1952), and lastly Federico Fellini’s La strada (1954).

Italian neorealist films were quite popular in Stalinist-era Poland (1945–53). As part of the propaganda strategy, they were used to create a negative image of life in western countries, thus confirming the omnipresent vision of ‘rotten capitalism’. The social criticism contained in neorealism was manipulated through a modal framework that explained to the Polish audiences all phenomena as a product of a bad social system based on injustice and exploitation. The aim of this article is to examine Polish reviews of two neorealist films: Ladri di biciclette (Bicycle Thieves) () and La terra trema (The Earth Trembles) () both presented to Polish audiences in 1951.

Abstrakt L’articolo prende in esame l’opera prima del regista Vittorio De Sica, in particolare i suoi primi quattro film: "Rose scarlatte" (1940), "Maddalena zero in condotta" (1941), "Teresa Venerdì" (1941) e "Un Garibaldino in convento" (1942). Oltre a collocare l’opera del regista italiano nel contesto politico, sociale e culturale dell’ultimo decennio del regime fascista, vengono analizzati i messaggi impliciti delle singole pellicole, abilmente nascosti sotto una maschera comica: p.es. l’emancipazione femminile, il carattere repressivo delle istituzioni e la problematica del "Strapaese e Straccittà". Nie tylko "Złodzieje rowerów" – faszystowskie Włochy w pierwszych filmach Vittoria de Siki Artykuł analizuje cztery pierwsze filmy Vittoria De Siki: "Szkarłatne róże" (1940), "Magdaleno, dwója ze sprawowania" (1941), "Teresa Venerdì" (1941) oraz "Un Garibladino in convento" (1942), pod kątem ich kontekstu politycznego, społecznego i kulturowego. Analiza poszczególnych dzieł pozwala ukazać ich zawoalowane przesłanie (np. dotyczące emancypacji kobiet, represyjnej natury instytucji oraz problematyki "Strapaese i Straccittà"), ukryte pod maską komizmu.

L'articolo esamina alcuni aspetti poco noti della marina creata ex novo dal governo cňrso ribelle di Pasquale Paoli, emersi in seguito all'analisi di numerose fonti in gran parte inedite. Un ruolo decisivo nella nascita e nello sviluppo della flotta "paolista" fu svolto dalle marinerie di Bonifacio, dei regni di Napoli e di Sicilia e dei presidi toscani sotto dominio napoletano. L'autore analizza i legami, non privi di tensioni, che unirono in gruppi di interesse alcuni dei principali corsari e contrabbandieri "paolisti" con uomini di mare, mercanti, mediatori e funzionari pubblici stranieri (napoletani soprattutto, ma non solo), mettendoli in condizione di usufruire delle risorse e delle ampie reti di relazioni proprie di questi soggetti. Un caso specifico, quindi, che permette tuttavia di gettare una luce piů ampia su fenomeni e problematiche proprie del mondo marittimo d'antico regime. In primo luogo il complesso intreccio di interessi che ruotavano intorno alla guerra di corsa e al contrabbando. In secondo luogo il ruolo strategico rivestito da alcune tipologie di merci e di risorse (come il sale e i disertori) e il diffuso ricorso a false identitÀ e "bandiere ombra". Si tratta di fenomeni che solitamente emergono con maggior vigore durante i periodi di guerra e risultano, quindi, particolarmente evidenti nel quadro del conflitto cňrso-genovese, grazie anche all'intreccio con la cruciale questione del riconoscimento della bandiera cňrsa.

L'autrice s'interroga sul senso attribuibile al tertium, riferimento spaziale e temporale ricorrente nell'opera junghiana. Partendo dal sintomo alla volta del simbolo e, parallelamente, procedendo dalle parole alle immagini, l'autrice presenta la funzione trascendente come ponte interpersonale e intrapersonale che permette alla diade analitica di creare con sacrificio lo spazio per accogliere contemporaneamente il reale e il potenziale, l'immanente e il trascendente. Il materiale del paziente, che rinasce ed č contenuto nel presente dal setting e dalla relazione analitica, diventa un altro terzo elemento, nuova energia psichica liberata e disponibile per proseguire il processo di guarigione di sé. In quest'ottica, anche la sabbia č presentata come terzo luogo possibile ove rappresentare e congedare vecchie e nuove forme di esistenza ed esperienza: toccando il complesso e lasciando risuonare gli archetipi, si procede sul sentiero dell'individuazione di cui paziente e analista sono a tratti alterni, guardiani e ladri.

With the onset of the Cold War, the cinema culture in the People’s Republic of Poland underwent rigorous transformation. One of its aspects was the new film import schema: most of the international sources dried up to be replaced, for the most part, by films from the Communist Bloc. However, Italian films constituted an important exception. This article investigates the critical reception of Italian neorealist films in Poland in the first decade after the war, focusing mainly on reviews published in Film, the most relevant Polish magazine dedicated to cinema culture. The first part of the article outlines critical debates on differences and similarities between neorealism and socialist realism. The latter part of the article focuses on the critical reception of Vittorio De Sica’s Ladri di biciclette (Bicycle Thieves) and Miracolo a Milano (Miracle in Milan), as evaluations of the Italian director’s cinema fluctuated during the Stalinist period and after the thaw.

Abstract Rocco Schiavone (2016–), la fortunata serie TV ormai giunta alla quarta stagione con una quinta in preparazione, nasce nel 2016 dagli omonimi romanzi di Antonio Manzini e viene trasmessa da Rai 2. Il programma, prodotto da Rai Fiction, Cross Productions, e Beta Film, registra una media di 3,3 milioni di telespettatori per episodio e uno share di oltre il 13% nella prima stagione. Nella seconda stagione mantiene tre milioni di spettatori per episodio e nella quarta uno share del 10.3% con 2.570.000 spettatori. Il successo si ripete anche all'estero e la popolarità dello scorbutico, sboccato, ma dal cuore d'oro vicequestore aggiunto della Questura di Aosta (interpretato da uno splendido Marco Giallini) continua a crescere dentro e fuori l'Italia. Grazie ai riscontri positivi della serie sul vicequestore trasteverino e alla notorietà di altre Rai Fiction come L'amica geniale e Il Cacciatore, i critici parlano di stagione d'oro della serialità italiana. Il grande successo di pubblico deve attribuirsi al fatto che il personaggio di Rocco Schiavone, duro con se stesso come con gli altri, scontroso, insofferente, nasconde dietro il suo cinismo un forte senso di umanità e una personalissima idea di giustizia. In queste pagine, si vuole infatti dimostrare come la fortuna di questa fiction sia dovuta a due fattori: una operazione di ibridismo operata all'interno del genere giallo, con una mescolanza delle formule e un assemblaggio di topoi provenienti da vari sotto-generi; e una continua contrapposizione tra giustizia e legalità, ovvero tra quello che il codice penale richiede a un rappresentante della legge, e le libertà che il nostro vicequestore si prende. Libertà che costringono lo spettatore a interrogarsi su una miriade di quesiti che lo pongono di fronte ai problemi dell'Italia di oggi, e esulano i confini della città di Aosta dove le storie si svolgono, forzandolo a ponderare su dilemmi universali: È giusto farsi giustizia da soli? È giusto ingannare i disonesti? È giusto rubare ai ladri per dare ai bisognosi? È giusto avere un codice etico personale e amministrare la giustizia? Che tipo di società è quella che permette abissi di povertà? Giustizia e Legge coincidono?

In this paper, a fuzzy adaptive linear active disturbance rejection control (Fuzzy-LADRC) is proposed for strong coupling and nonlinear quadrotor unmanned aerial vehicle (UAV). At present, UAV conveys new opportunities in the industry, such as power line inspection, petroleum conduit patrolling, and defects detection for the wind turbine, because of its advantages in flexibility, high efficiency, and economy. Usually, the scene of the UAV mission has a high risk, and there are internal sensor noise and unknown external disturbance. Thus, the attitude stability and anti-interference ability of UAV are especially essential. To solve the strong coupling problem of UAV, the dynamics model of UAV is established via the Newton-Euler method, and the coupling part of dynamics is modeled as an internal disturbance. According to the function of linear active disturbance rejection control (LADRC) parameters, a Fuzzy-LADRC is proposed to improve the dynamic performance of the system. The proposed control method makes full use of the adaptive ability of the fuzzy controller and the anti-interference ability of LADRC to the nonlinear and strong coupling systems. As we know, this is the first time that Fuzzy-LADRC has been used in UAV control. In the simulation, the performance indicators of four controllers, including Fuzzy-LADRC, LADRC, PID, and Fuzzy-PID are compared and analyzed. The results indicate that the average response speed of Fuzzy-LADRC is 12.65% faster than LADRC, and it is 29.25% faster than PID. The average overshoot of Fuzzy-LADRC is 17% less than LADRC and 77.75% less than PID. The proposed control method can significantly improve the response speed and anti-interference ability of UAV.

This paper investigates the stability and performance of the linear active disturbance rejection control (LADRC)–based system with uncertainties and external disturbance via transfer functions and a frequency-domain view. The performance of LADRC is compared with the state-observer-based state feedback control (SOSFC) and state feedback control (SFC). First, the transfer functions and the error transfer functions for LADRC, SOSFC, and SFC are studied using the state-space method. It is proven that the LADRC-, SOSFC-, and SFC-based closed-loop systems have the same transfer function from the reference input to the output and achieve the same control effects for the nominal system. Then, it is proven for the first time that the LADRC has a better anti-interference ability than the SOSFC and SFC. Besides, the asymptotic stability condition of LADRC-based closed-loop system considering large parameter perturbations is given first. Moreover, the sensitivity analysis of the closed-loop system is carried out. The results show that the LADRC has stronger robustness under parameter perturbations. According to the results, we conclude that the LADRC is of great disturbance rejection ability and strong robustness.

In this work, a novel fractional-order extended state observer (FOESO)-based linear active disturbance rejection control (LADRC) method is firstly proposed for a hypersonic vehicle (HV) to address the measurement noise problem. The uncertainty and external disturbance of an HV was discussed and addressed by the active disturbance rejection control and many different control methods in recent decades. However, the research of an HV with measurement noise is insufficient. For the LADRC, the anti-noise ability is highly dependent on the bandwidth of the extended state observer (ESO). Meanwhile, the control performance of the LADRC is relevant to the bandwidth. The FOESO is presented, aiming to address the tradeoff of the control performance or noise suppression. The FOESO-based LADRC (FOESO-LADRC) introduces fractional calculus. It can enhance the anti-noise ability with little influence on the control performance. The simulation results show that the FOESO-LADRC has a significant improvement in the noise suppression. In addition, compared with the LADRC, it obtains a better solution to address the tradeoff between the bandwidth and noise impact.

Photovoltaic grid-connected power generation systems are easily affected by external factors, and their anti-interference performance is poor. For example, changes in illumination and fluctuations in the power grid affect the operation ability of the system. Linear active disturbance rejection control (LADRC) can extract the “summation disturbance” information from the system and eliminate the disturbance at the fastest speed by controlling the signal before it affects the final output of the system. In this paper, an improved linear ADRC based on the principle of deviation control is proposed, and the voltage outer loop is controlled by an improved LADRC. This improved LADRC takes the deviation between each state variable and its observed value as the regulation basis for each state variable of the linear extended state observer (LESO). Based on the analysis of the bode diagram in the frequency domain, it can be concluded that, compared with the unimproved LADRC, the new LADRC has better disturbance rejection performance. The simulation results show that the control performance of the new, improved LADRC is better than that of the unimproved LADRC under different operating conditions, and it has better stability performance and anti-disturbance performance.

As a new disk-shaped autonomous underwater vehicle (AUV), the autonomous underwater helicopter (AUH) is devoted to subsea operations, usually diving into the seabed and docking with a subsea docking system. Due to the motion control’s performance, the AUH’s stability and steady-state accuracy are affected remarkably while docking. Moreover, considering the difficulties of hydrodynamic modeling of AUHs, the classical model-based control method is unsuitable for AUHs. Moreover, there is a large gap between the hydrodynamic simulation results and real situations. Hence, based on the data-driven principle, the linear active disturbance rejection control with a tracking differentiator (LADRC-TD) algorithm is employed for AUH depths and heading control. As the simulation experiments prove, LADRC and LADRC-TD have better anti-interference performance when compared with PID. According to the pool experiments, overshoots of the LADRC-TD are 20 cm and 3° for the depth control and heading control, respectively, which are superior to PID and LADRC. Meanwhile, the steady-state accuracy of the LADRC-TD is ±21 cm and ±2.5° for the depth and heading control, respectively, which is inferior to PID and the same as LADRC.

Unmanned Aerial Vehicle (UAV) are currently gaining popularity. This paper proposes a method to apply Linear Active Disturbance Rejection Control (LADRC) to Quadrotor Unmanned Aerial Vehicle (QUAV) controller to optimize the traditional PID controller. Firstly, the application and shortcomings of traditional PID control in UAV are introduced, and the LADRC method is proposed. Then linear simplification and Parameter Setting of ADRC are carried out. In the Simulink environment, according to the mathematical model of the QUAV, a QUAV dynamics simulation platform is established. Finally, according to different control channels, different control algorithms are designed, and tracking models are introduced in various attitudes to simulate and verify the control effect of LADRC. The results show that the LADRC controller is effective, the LADRC can be effectively combined with the traditional PID control. The application in the QUAV can realize more precise QUAV speed tracking control and the stable flight of the QUAV. Compared with the traditional PID controller, under the experimental conditions of this paper, the LADRC controller has more precise control accuracy and more efficient control efficiency.

Abstract The Internet of Things (IoT) systems require power management modules to have the characteristics of low power consumption, high conversion efficiency, high integration, stable output, and good dynamic response. Due to its ease of tuning and superior control performance, linear active disturbance rejection control (LADRC) is an attractive design option. Yet, to date, due to its high complexity, LADRC has been used in software systems, while little effort has been made in its hardware implementation. In this work, we investigate and explore efficient hardware implementation of the LADRC algorithm. A fully integrated digital LADRC controller for DC-DC Buck converters is synthesized with UMC 55 nm CMOS process. Its input voltage is 5V, stable output voltage is 2V, and rated operating current is 100mA. To our best knowledge, this is the first work to implement LADRC algorithms in hardware. Simulation results show that the LADRC controller is superior to the PID controller in the terms of start-up time, line regulation, load regulation.

This paper proposes the analysis and design of the linear active disturbance rejection controller (LADRC) for the pitch angle model of a large wind turbine generator (WTG). Since the transfer function of the pitch control system exhibits nonminimum-phase characteristics, the parameters of LADRC are difficult to tune using the conventional bandwidth method. On the basis of PI controller parameters to first-order LADRC parameters, an optimization problem is proposed in this paper to find the parameters of an LADRC for the pitch control system under the constraint of robustness measure, and the extremum-seeking (ES) algorithm is used to solve the problem. Simulation results show that LADRC can achieve better tracking and disturbance rejection performance than traditional PI control without loss of robustness against time delay.

The solid ducted rocket ramjet (SDR) system faces many disturbances in the process of operation, and the linear active disturbance rejection controller (LADRC) has been widely used in engineering to solve such problems. However, the SDR also has strong nonlinearity, which brings a great challenge to the application of the LADRC in the gas flow regulation of the SDR. And the problem of fast adjustment of the “compensation factor” is one of the main difficulties in LADRC. In this paper, under the LADRC frame, the gas generator system’s closed-loop stability of the SDR was analyzed and the range of compensation factors had been calculated, and then, the “gap factor” was introduced and the “cross-iteration” method was used to quickly map out the “compensation factor” in the multilinear model controller based on the variation of the zero-point position of the system and the gap metric between adjacent set points. This greatly simplifies the parameter tuning process of the LADRC when it was applied to strongly nonlinear systems. Finally, through the comparison of simulation with adaptive PI controller and model-assisted LADRC (M-LADRC), the results have shown that the control method designed in this paper can obtain satisfactory performance and has a good engineering application prospect.

The energy storage inverter system has the characteristics of nonlinearity, strong coupling, variable parameters, and flexible mode switching between parallel and off grid. In order to improve the control performance of the grid-side inverter of the energy storage system, an improved Linear Active Disturbance Rejection Control (LADRC) based on proportional differentiation is proposed to replace the traditional LADRC in the voltage outer loop control. In this paper, the observation gain coefficient of the sum of the disturbances of the traditional Linear Extended State Observer (LESO) is improved to a proportional differentiation link, which effectively reduces the degree of the disturbance observation amplitude drop and the phase lag, and increases the observation bandwidth of LESO. Compared with traditional LADRC, it not only improves the observation accuracy of LESO for disturbance, but also improves the anti-interference performance of LADRC. Finally, the control effects of improved LADRC and traditional LADRC on low-voltage ride-through at different degrees are analyzed and compared through simulation, which proves the rationality of the controller designed in this paper.

The lever-type electric erection system is a novel kind of erection system and the experimental platform in this paper operates with varying loads and low-resolution encoder. For high accuracy trajectory tracking, linear active disturbance rejection control (LADRC) is introduced. An approximate model, consisting of the servo system configured at velocity control mode and the lever-type erection mechanism, is built by means of system identification and curve fitting. Reduced-order LADRC based on the further simplified model is proposed to improve tracking accuracy and robustness. As comparisons, traditional LADRC and PID with high-gain tracking differentiator (HGTD) are designed. Simulation and experimental results indicate that reduced-order LADRC can realize higher trajectory tracking accuracy with low-resolution encoder and has better robustness to variation in erection loads, compared with traditional LADRC and PID with HGTD.

In wind power systems, LCL inverters have technical problems. First of all, they are non-linear systems and are no longer adapted to the superposition principle; secondly, the coupling is great; finally, it is easy to be interfered by the outside world, and the interference mainly comes from voltage fluctuations and nonlinear loads on the grid. Therefore, it is difficult to control the output result, and then the improved linear active disturbance rejection control (LADRC) is applied. The main improvement of the improved LADRC lies in the linear extended state observer (LESO). Introducing the total disturbance differential signal in LESO, and in order to improve the ability to suppress high-frequency noise, a series of first-order inertia link was applied. The analysis method in this article is mainly frequency domain analysis, under the condition of obtaining LADRC closed-loop transfer function and frequency band characteristics, theoretical analysis of LADRC tracking estimation ability, disturbance suppression ability, and stability. A large number of experimental simulation results verified the superiority of improving LADRC. The main manifestation is that the improved LADRC not only has a fast response speed but also has a strong ability to suppress disturbances and has a good noise suppression effect in high frequency bands.
