Abstract:

In order to improve the working efficiency of the driving system of electric vehicles equipped with permanent magnet synchronous motor (PMSM), enhance the stationarity and response speed of the motion process, so as to improve the overall dynamic control performance of the driving system of electric vehicles, in this paper, switching functional hybrid control technology is proposed and designed based on the analysis of electric motor operating characteristics and feedback control principle derivation. The control technology can effectively improve the dynamic and static performance and robustness of the vehicle motor control system. In order to verify the effectiveness of the proposed control technology, a simulation model is established for simulation and analysis. The experimental platform is built for experimental verification. The simulation and experimental results show that the proposed control technology has the advantages of fast output response, no overshooting or oscillation, which can improve the efficiency of the motor, optimize the output characteristics of its drive system, and enhance the control performance of the electric vehicle drive system.
