Abstract:

The paper describes the approach and methodology for the numerical assessment of the quality of periodic processes. With regard to their particular case the processes of selfoscillations, on the basis of the proposed approach, the problem of optimization of the control system is formulated and possible ways of solving it are shown. The practical implementation of the approach is possible when synthesizing a control system, as well as in the variant of automatic adaptive control during its operation. The proposed solutions are based on the use of methods of the theory of entropy potentials. The implementation of the proposed solutions will improve the quality of monitoring of periodic processes and the efficiency of regulation systems in selfoscillation modes.

Abstract:

One of the biggest problems in pneumatic system design is over design. Thus, the results are excessive in costs of the initial investment and it requires too much energy. This article describes the development of expert system based pneumatic design system, PNEUDES (PNEUmatic Design Expert System), prototype that enables the user the optimal design of pneumatic system. Once the design requirements such as cylinder type and work load, etc. are input to the system, optimal cylinder specifications with standardized order-based size, valves types, and necessary accessories are all determined. Also the configuration information such as the connectivity among components and cylinder image data are supplied to the user. It can also help the novice of pneumatic design. The rule-based reasoning approach is used as a reasoning strategy with Intelligent Rule Element shell.

Abstract:

The paper proposes a large approach to pneumatic systems starting from the mathematical laws, written in the form of differential equations, which govern the operation of pneumatic systems and continuing with the simulation model. The concept of integrated design includes all approaches, needed for an optimal and deep system understanding, such as modeling, simulation and control. Pneumatic actuators have a nonlinear functionality because of air compressibility, the existing frictions and the valves nonlinearities. Because of these, they are used in high speed applications and simple positioning systems. Thus, the mathematical analyses of pneumatic systems have received a special attention. The differential equations were implemented in Matlab Simulink, and the model input represents the voltage on the electromagnetic valve, and the output seen on the "scope" represents the movement of the piston pneumatic axis. Some control algorithms are implemented and applied to the model and seen the basic differences.

Abstract:

The pneumatic valves are widely used in the actual industrial production, and their practical performances are very important to the control system. Traditionally, the common PID controller is widely used in the control of the pneumatic valves. Due to the strong nonlinearity of the pneumatic valve, the control effect of the PID method for the pneumatic valve is below what is desired. In order to address this problem, a fuzzy PID control scheme is presented to be used in the pneumatic system in this paper. Simulation results and the practical control effect show that this kind of compound control structure has better performance than the classical PID control method and satisfactory effects have been obtained.

Abstract:

In order to make sure what factors have an effect on condensation, a mathematical model has been established for the discharging process of a pneumatic system using the fluid grid theory, an analytic equation has been derived to determine the maximum humidity of air during discharging of pneumatic system, and an analytic equation has been established as the first necessary condition for the determination of internal condensation in a pneumatic system. Flowing air may produce water droplets in a pneumatic system when the system satisfies the first necessary condition. An analytic equation has been developed as the second necessary condition for determination of internal condensation in a pneumatic system by introducing stroke and establishing an analytic equation for the stroke. The water droplets produced by satisfaction of the first necessary condition form drops of water inside the system when the system satisfies the second necessary condition. Internal condensation does not occur when the system does not satisfy the first necessary condition, and internal condensation occurs only when the system satisfies both conditions at the same time. The experimental results indicate that the points of internal condensation, external condensation and no condensation exhibit a regular distribution on the plane formed by the dimensionless volume of the discharging pipe and the average velocity of air, and the plane can then be divided into regions, providing a graphic discrimination method for determination of condensation in a pneumatic system.

A design experiment involving the addition of the hydraulic line to the pneumatic cylinder to trigger dynamic phenomena in the cylinder is presented. Thanks to this, it is possible to limit the occurrence of the stick-slip phenomenon, often occurring in linear actuators at low mutual speed of the piston and the cylinder. The purpose of this operation is to obtain the possibility of precise control of the piston position of the pneumatic cylinder without using complicated systems using algorithms with nonlinear functions.

Pneumatic cylinder systems have the potential to provide fast and reliable motion characteristics with large power output to weight at low cost to benefit ratios. To properly utilize pneumatic cylinder systems in industrial applications (especially in control situations), mechanical engineers must appreciate and understand the dynamic characteristics of these devices. In this paper, the linearized continuous time dynamics of a pneumatic rodless cylinder system are examined. Two transfer functions, based upon the midstroke and off-centre operation conditions respectively, are presented.

Abstract:

Automobiles have been used to move human beings or things and the automobile technology has been developed within the last few years. The traffic accidents are increasing as automobile production has been increasing. The number of casualties during the vehicle accidents is very large as compared to the other causes of death. It is important to prevent accidents and to protect the driver and pedestrian when accidents occur. Though there are different causes for these accidents but proper technology of braking system and technology to reduce the damage during accident (such as pneumatic bumper system) can be effective on the accident rates. Therefore, pre-crashing system is demanded. Automotive safety has gained an increasing amount of interest from the general public, governments, and the car industry. The pre-crash system is to prevent accidents on roads with poor visibility by using sensor network to find invisible vehicles, which are to be detected by autonomous on-vehicle sensors. The pre-crashing system is processing the sensor data and controlling the vehicle to prevent accidents and accidents caused by careless driving. The pneumatic system is simple and easy in operation and hence can be used in automation industry.

This paper deals with the parametric study of a twin-pipe graduated release railway air brake system. The air brake model is based on the analysis of a pneumatic train circuit and a vehicle pneumatic circuit. The parametric study includes the effect of variation of the pneumatic train circuit and vehicle pneumatic circuit parameters. This shows that the computer simulation can be used to predict the performance while varying the design parameters during a brake application. The information is of vital importance for train operation and for laying maintenance and manufacturing tolerances of air brake system design parameters.

Abstract:

This paper presents a novel control design, developed to realise fast and accurate positioncontrol of a pneumatic actuator using inexpensive on/off solenoid valves. In contrast to conventional controlmethods, the proposed control method operates chatter free, based on air compression. The controlprinciple was developed by investigating the dynamics of a pneumatic actuator with an identifiedmathematical model. This new approach is applied to a pneumatic double acting cylinder, controlled by apair of 5/3 way directional single solenoid valves. The described closed-loop circuit copes with thediscontinuities associated with the valve’s switching dynamics, and relatively long response time. Theexperimental apparatus uses an analogue displacement encoder for metering the piston’s position andvelocity, and doesn’t incorporate pressure sensors thus ensuring a low cost system design. The results ofexperiments with various step responses show that the proposed control method performs well. Themeasured steady-state position errors are equal to the used potentiometer’s travel resolution, which is 0,01mm. Therefore this novel control and the related pneumatic system design could be a cost effectivealternative to the servo-pneumatic positioning systems.

Abstract:

One of the typical features of a pneumatic servo is a relatively high compliance due to air compressibility. This feature may be useful for constrained tasks such as deburring, polishing, and assisting humans, in which the relationship between position and force is important. If this relationship of a pneumatic servo becomes actively controllable, it can be effectively applied to these tasks. In order to control this relationship, an impedance control concept has recently been proposed. The impedance of the overall control system depends not only on the manipulator but also on the manipulated object of which the characteristics are usually unknown. Therefore, to attain the desired impedance over extensive operating conditions, an adaptive control strategy is required. This paper proposes an impedance control method of a pneumatic servo, using a position based approach, where an adaptive position control system is constructed inside the force feedback loop. The proposed method is applied to an experimental pneumatic servo system comprised of a pneumatic cylinder, electro-pneumatic proportional control valves, and a spring object. From the experiments, the following has been verified: 1) both static stiffness and dynamic impedance of the pneumatic servo system can be independently regulated by setting a desired reference model; 2) the impedance can be held constant with changes in system parameter such as object stiffness; and 3) the instability problem for the low stiffness setting can be overcome by setting high damping in the reference model. The proposed impedance control method may prove to be effective for both improving a pneumatic servo and developing its new applications.

Abstract:

Differentiation of the force applied to the cobs of seed corn in the process of threshing allows minimizing the amount of macro- and micro-damage to the grain, which maintains the potential yield level of this crop. (Research purpose) To develop an automatic control system for active pneumatic elements of the deck of the threshing-and-separating unit capable of varying the pressing force of the spikes applied to the cobs of seed corn in different parts of the threshing chamber to minimize the crop damage. (Materials and methods) The authors have used the methods of system analysis, designing the operating algorithms of automated mechanical systems, electronics and general electrical engineering. (Results and discussions) The authors offer an advanced design of the threshing-and-separating unit for seed corn. The design features an active pneumatic deck with an automatic control system varying the pressing force of separate deck spikes to the cob grain directly in the course of threshing. For air inflating and lowering, two valves are installed in each of the 16 airbags, 32 control relays being used. The operation process is automatized through the Atmega 2560 controller regulating the amount of pressure in the airbags forcing the spikes against the grain in the process of threshing. The authors propose a schematic diagram describing the operation algorithm of the controller with pressure control units in deck airbags. By programming the controller, an operator can change the amount of pressure in the airbags, thus adjusting the force of direct and precise pressing the deck spikes to the corn cobs, for any airbag and in any part of the deck. (Conclusions) It has been determined that the destructive pressing force of 55 Newtons can be achieved in certain combinations of the membrane thickness, the pressure in the airbags and the pressing depth of the spikes. The proposed design of the threshing device with a system of automated pressure control in the deck airbags allows varying the force of threshing, which minimizes the amount of macro- and micro-damage to the seed corn grain and thus maintains the potential yield level of this crop.
