A position sensorless control strategy for the Interior Permanent Magnet Synchronous Motor (IPMSM) is proposed, which operates across the full speed range. This strategy integrates the high-frequency square wave voltage injection method suitable for low-speed regions with the super-twisting sliding mode observer method appropriate for high-speed regions. To address the issues of speed jumps and significant errors at the switching critical points when using the weighted average switching method in the low-to-high speed transition zone, a smooth switching control methodbased on fuzzy control theory is introduced. Furthermore, to enhance the speed control performance of the IPMSM, a sliding mode speed controller is designed, which incorporates a novel exponential convergence law and a sliding mode disturbance observer. Finally, the effectiveness of the proposed control strategy is validated through simulation experiments.
② 双 S形隶属度函数:通过渐进变化能够保持较好的平滑性。在区间400~1 000 r/min内,由于输入变量变化较大,控制系统需平稳过渡以避免振荡或过冲。因此,在该区间内,本文采用了五个双S形隶属度函数,分别对应“NM”、“NS”、“ZO”、“PS”和“PM”5个模糊集合。双S形隶属度函数的形式为:
