Abstract High-speed permanent magnet synchronous generator (HSPMSG) has the advantages of high power density, small size, and lightweight, and is widely used in many applications. However, the conventional double closed-loop control has poor control performance as the output voltage fluctuates with the change of load, which is difficult to meet high-performance applications. For the above problems, some advanced control methods have been proposed, but most have limited ability to suppress load disturbances. In order to improve the ability of the system to resist load disturbance, this paper proposes a voltage stabilization control method based on the disturbance observer compensation.
Firstly, a dynamic mathematical model of the permanent magnet synchronous generator system is established. Secondly, considering the influence of load changes on voltage stability, this paper considers the load current as a system disturbance, and a disturbance observer based on the super-twisting algorithm is designed. To improve the response speed of the disturbance observer, the super-twisting algorithm is improved, and its stability is demonstrated by the Lyapunov stability theory. Then, to further improve the tracking and immunity of the conventional PI controller, a two-degree-of-freedom voltage loop PI controller is designed, and its control parameters are analyzed. Finally, the load current observed by the disturbance observer is converted and feedback to the output of the voltage loop so that fluctuations in the DC-side voltage during load changes can be suppressed. The system stability is analyzed by frequency domain analysis, and the results show that with load current feedforward, the disturbance of the system by the load current can be effectively suppressed. To verify the correctness and effectiveness of the proposed control method, simulations and experiments are carried out based on a HSPMSG. The simulation results show that the voltage fluctuation is reduced from 2.5 V to 0.2 V, and the settling time is reduced from 20 ms to 5 ms when the load is suddenly changed. It is demonstrated that the proposed control method can significantly suppress the voltage fluctuation during load switching, shorten the voltage settling time, and improve the dynamic performance of the output voltage. To further highlight the advantages of this control method, an experimental platform for a high-speed permanent magnet synchronous generator system based on the TMS320F28377D is built, and a series of experiments are conducted. According to the experimental results, the voltage drop is 11 V, and the settling time is 110 ms when the conventional control method is used. In comparison, the voltage drop is reduced from 11 V to 3.5 V, and the settling time is reduced to 42 ms with the proposed control method. The experimental results show that the control strategy proposed in this paper can effectively suppress the voltage fluctuation when the load changes and improve the dynamic performance of the system.
The following conclusions can be drawn from the simulation and experimental results: (1) Based on the improved super-twisting algorithm, the disturbance observer can observe the change of load disturbance in real time and has high observation accuracy. (2) The control method proposed in this paper can significantly improve the dynamic performance of the system, which can effectively suppress the voltage fluctuation when the load changes and shorten the settling time of the voltage fluctuation.
