摘要
针对传统滑模算法永磁同步电机无速度传感器存在转速抖振和鲁棒性差的问题,提出超螺旋控制算法与模糊控制相结合的永磁同步电机转速观测方法。首先,利用超螺旋滑模收敛速度快,模糊控制可以解决超螺旋算法中边界函数上界获取困难的问题;其次,通过模糊算法输出增益,提高了系统的动态特性和鲁棒性;最后,对所提出的算法进行验证。应用该算法,转速误差不超过1%,控制系统的超调量为4%,滞后时间不超过0.003 ms。
Aiming at the problem of speed chattering and poor robustness of sensorless permanent magnet synchronous motor(PMSM)based on traditional sliding mode algorithm,a speed observation method of PMSM based on the combination of super-spiral control algorithm and fuzzy control is proposed.Firstly,the fuzzy control can solve the problem of obtaining the upper bound of the boundary function in the super-spiral algorithm by using the super-spiral sliding mode,and secondly,output the gain through the fuzzy algorithm,the dynamic characteristics and robustness of the system are improved.Finally,the proposed algorithm is verified.With this algorithm,the speed error is less than 1%,the overshoot of the control system is 4%,and the lag time is less than 0.003 ms.
