摘要
为了提升永磁同步电机转速控制的响应速度和抗扰能力,提出一种重复滑模控制算法。对永磁同步电机的数学模型和滑模控制结构进行分析,将滑模控制和重复控制策略相结合,并引入滤波器和动态补偿器,构成一种改进型的重复滑模控制方法。仿真结果表明,在负载发生扰动突变时,重复滑模控制的转速下降幅度仅为滑模算法的27%左右,抑制扰动的过渡时间仅为滑模算法的20%左右,验证了重复滑模控制具有更快的响应速度和更强的抗扰能力。
In order to improve the response speed and anti-interference ability of permanent magnet synchronous motor speed control,a repetitive synovial control algorithm is proposed.This paper analyzes the mathematical model and synovial control structure of permanent magnet synchronous motor,combines synovial control and repetitive control strategy,introduces a filter and a dynamic compensator to form an improved repetitive synovial control.The simulation results show that when the load disturbance mutation occurs,the speed reduction of repetitive synovial control is only about 27%,and the transition time to suppress the disturbance is only about 20%of those of synovial algorithm.It is verified that repetitive synovial control has faster response speed and stronger anti-interference ability.
