In the process of gear shift and speed regulation of electric vehicles, in order to solve the contradiction between short speed regulation time and small gear shift impact in permanent magnet synchronous motor speed regulation system, a modified tracking differentiator-decoupled active disturbance rejection controller (MTD-DADRC) was proposed. It was applied to the speed loop control of permanent magnet synchronous motor vector control system. The decoupled active disturbance rejection controller was designed through the frequency domain analysis of the ADRC system. The decoupled active disturbance rejection controller improves the stability and anti-noise ability of the system and expands the parameter selection range of the tracking differentiator. On this basis, the tracking differentiator was improved by introducing nonlinear function and terminal attractor function to improve the speed tracking performance of the motor. Compared with the traditional PI controller, the MTD-DADRC proposed in this paper has the advantages of high control accuracy and good tracking performance. Thus, it can effectively shorten the gear shift and speed regulation time while reducing the gear shift impact.
