摘　　要：永磁同步电机调速控制系统中,传统PID控制已无法满足高速、高精度应用领域系统快速响应和无超调的控制要求。针对积分环节的作用特点,要求系统在较大偏差时能够减小积分作用,在较小偏差时能够增强积分作用,提出一种改进的变速积分PID控制算法,将其应用到永磁同步电机控制系统速度环。通过仿真试验结果表明,改进变速积分PID控制能够有效降低超调量,同时进一步提高调速系统响应速度,具有更强的抗干扰能力。For the speed control system of permanent magnet synchronous motor（ PMSM）,traditional PID control could not achieve ideal performance of low overshoot and rapid response in high speed and high precision application. In this paper,duo to the characteristic of integrator,it should be reduced when the system deviation is large and strengthened when the system deviation is small. A variableintegrator PID control algorithm was designed to apply in the speed control of PMSM. The simulation results show that the above variable-integrator PID algorithm not only reduced the overshoot,but also improved the rapidity of regulating process,it had stronger anti-interference performance.
