Purpose Predictive controllers and permanent magnet synchronous motors (PMSMs) got more attention over the past decades thanks to their applicable features. This paper aims to propose and verify a method to design a predictive current controller with consideration of motor characteristics obtained from finite element analysis (FEA). Design/methodology/approach Permanent magnet motor parameters and its maps can be calculated by means of FEA. The model takes into account magnetic saturation and thermal electro-magnetic properties. For each dq current vector and each position, self and mutual inductances are calculated. Based on co-energy method and fundamentals of coordinate transformation dynamic and static, dq inductances are obtained. These are used in classical and modified dead-beat current controller equations. Findings To sustain good features of a controller over higher current regions, it is necessary to adapt control law of a dead-beat controller. After its modification, control quality can be superior over classical solution in high saturation regions. The transient simulations of controller and motor give accurate results. Originality/value Common predictive current controllers use nominal motor parameters in their equations. The authors proposed a modified dead-beat current controller to improve the control quality. There is no need to apply self-tuning algorithms, and implementation of the controller is not much more complicated than that of the classical controller. Designer of a control system can obtain required data from motor designer; in design process of modern machines such data are often already available. The proposed methodology increases control quality of the presented dead-beat controller.

This paper studies the instantaneous output power characteristics of photovoltaic inverters and its flexible power control strategy under unbalanced grid faults. Then the optimal parameters model of the power control is established with minimum integrated fluctuation amplitude of the active and reactive power as a goal when the constraint of the output current harmonic distortion of photovoltaic inverters is taken into account. Finally, the optimal power control of photovoltaic inverters based on dead-beat current tracking is realized and the feasibility of the proposed control strategy is verified with the power system transient software PSCAD/EMTDC.

Abstract To solve the problem that the torque pulsation is serious due to the large current error in the period when the duty cycle is calculated by the deadbeat method in the duty cycle dual-vector model predictive current control method, a vector switching method is proposed. The control objective of the proposed method is not to equate the predicted torque current with the reference value under the dead-beat idea, but to reduce the torque current control error by changing the switching time of the voltage vector and ensuring the symmetry of the positive and negative current errors. By deducing the duty cycle, the maximum current errors in a single control cycle before and after vector switching is compared and analyzed. The vector switching method is verified on the Simulink simulation platform and compared with the duty cycle double vector method. The results show that the vector switching method can effectively reduce the intra-cycle torque current tracking error and realize the optimal process control in each cycle.

The present current control method in doubly fed induction generator cannot realize the segmented grid-connected current control, it’s hard to effectively control the current in doubly fed induction generator. Therefore, a current control method in doubly fed induction generator under low switching frequency is proposed in this paper. Which means to build a mathematical model of the doubly fed induction generator under low switching frequency to analyze the parameters of doubly fed induction generator filter. Then the parameter values of the filter can be obtained. The current in generator can be predicted by adopting the double-sampling predict method. And the current control in generator can be improved according to dead beat control. Then the on-line identification of current parameters by least square method is needed to finish the current control method in doubly fed induction generator under low switching frequency. The experimental results show that the proposed method realized the segmented grid-connected current control in doubly fed induction generator.

The primary aim of this thesis is to investigate the small-signal dynamic performance of high voltage direct current (HVDC) transmission links based on voltage source converter (VSC) technology operating in parallel with the existing longitudinal Australian power system. This thesis presents the principle design methodology to achieve robust controllers for VSCs including inner current controller, outer power and voltage controllers as well as the supplementary damping controllers for enhancing the small-disturbance rotor-angle stability of a weak multi-machine power system with embedded VSC-HVDC links. Three types of linear current controller schemes (proportional-integral, proportional-resonant and Dead-Beat schemes) are investigated and discussed in detail to identify the most suitable control method. Due to its wider bandwidth and superior performance under unbalanced operating conditions, the Dead Beat current controller is set as the inner current controller that has not been analysed in detail in the literature. A new methodology for the selection and optimization of the parameters of the proportional-integral compensators in the various control loops of a VSC-HVDC transmission system using a decoupled control strategy is also proposed in this thesis. It was found that the new methodology is effective in a relatively strong system. However, since the method did not take various operating conditions and system disturbances into account, it will not be effective in a relatively weak system. The analysis shows that the design of robust outer loop controllers is challenging due to the limited bandwidth of the inner current controller in a weak AC system. Therefore, the second primary objective of the project was to develop a simple fixed parameter controller, which can perform well over a wide range of operating points within the active/reactive power (PQ) capability chart of the VSCs. To achieve this second objective, various grid conditions including various Short Circuit Ratios (SCRs), different X/R ratios and PQ capabilities of the VSC system were studied. To support the primary objectives, a detailed higher order small-signal model of the DB controlled VSC is developed and systematically verified. As an original contribution, the study developed a new methodology to linearize the modulator/demodulator blocks which are used to develop the small signal models for several key components such as the sampling block, the delay block and the DB inner current controller. The initial values of the PI/PID compensator parameters are obtained by applying the classical frequency response design methods to a set of detailed linear models of the open-loop transfer functions of the VSC-HVDC control system. It was concluded that an iterative process may be required after examining the co-operation performance of these controllers designed. In the final chapter of this thesis, the small-signal rotor-angle stability of a model of the Australian power system with embedded VSC based HVDC links was examined. For the analytical purposes of this thesis a simplified model of the Australian power system is used to connect the high capacity, but as yet undeveloped, geothermal resource in the region of Innamincka in northern South Australia via a 1,100 km HVDC link to Armidale in northern New South Wales. It is observed that the introduction of the new source of geothermal power generation has an adverse impact on the damping performance of the system. Therefore, two forms of stabilization are examined: (i) generator power system stabilisers (PSS) fitted to the synchronous machines which are used to convert geothermal energy to electrical power; and (ii) power oscillation damping controllers (PODs) fitted to the VSC-HVDC link. In the case of the PODs two types of stabilizing input signals are considered: (i) local signals such as power flow in adjacent AC lines and (ii) wide-area signals such as bus voltage angles at key nodes in the various regions of the system. It was concluded that the small-signal rotor-angle stability of the interconnected AC/DC system has been greatly enhanced by employing the designed damping controllers.
