Applications of a Novel Integral Sliding Mode Controller on PEV Speed Control System Driven by PMSM

针对PID控制的永磁同步电机(Permanent Magnet Synchronous Motor,PMSM)驱动的纯电动汽车(Pure Electric Vehicles,PEV)调速系统性能的不足,提出一种新型积分滑模控制算法用于PEV调速控制器。依据永磁同步电机(PMSM)的数学模型和纯电动汽车(PEV)的动力学方程,在MATLAB中搭建了PMSM驱动的PEV调速系统的仿真模型并验证新型积分滑模调速控制器的效果。仿真表明,相比于采用PID控制算法的PEV调速系统,基于该控制算法的PEV调速系统拥有更小的超调量和稳态误差,且转速追踪响应时间更短。

Aiming at weaknes of tlie performance of pure electric vehicles driven by permanent magnet syn-chronous motor,a improved integral sliding mode control algorithm is proposed. According to the mathematical model of PMSM and the dynamical equation of PEV, the simulation model of PEV driven by PMSMMATLAB which to verify the effect of novel algoritlim. Simulation shows that compared the improved integral sliding mode controller has smaller overs!ioot and steady - state eror, and the speedtracking response time is shorter.
