摘要 本文针对开关磁阻电动机调速系统转矩脉动和噪音比较大的特点,根据变结构控制理论,提出采用滑模-PI变结构的控制策略。理论分析和仿真研究表明,对开关磁阻电动机调速系统实行变结构控制,有助于克服非线性因数对系统的影响、减小转矩脉动、降低噪音和提高系统的鲁棒性。而在误差很小的范围内,切换为PI控制,则有助于克服滑模存在的颤震问题,提高系统的稳态精度。 Based on slide mode variable structure(VS) principle, a novel control strategy of PI-VS for switched reluctance motor (SRM)is proposed in order to reduce torgue ripple and noises. Theoretical analysis and simulation results show that this new scheme enables the system to be of good robustness.
