摘要：
Aiming at the problems of large interference and severe environmental impact on permanent magnet synchronous motor for electric vehicle, a third-order sliding mode active disturbance rejection control method with filter compensation was proposed. Firstly, a sliding mode controller considering unknown disturbance was designed in the speed loop, which avoided the problems of complex calculation model and poor disturbance rejection performance caused by using the maximum torque current ratio control strategy. Then, combining sliding mode control with active disturbance rejection control, the total disturbance of the compensation system was estimated in real time without establishing an accurate mathematical model, which reduced the problem of large chattering caused by sliding mode control to the greatest extent. At the same time, the phase delay caused by filtering various signal interferences by low-pass filter in the speed loop was compensated to improve the system control accuracy, and stability of the proposed control system was verified by Lyapunov theory. Simulation and experimental results show that compared with sliding mode control and sliding mode active disturbance rejection control, the proposed method has better disturbance rejection performance and faster response ability, and is more suitable for the application of permanent magnet synchronous motor for electric vehicle. © 2021, Harbin University of Science and Technology Publication.
