针对参数不确定分数阶永磁同步电机混沌系统,研究在含非线性不确定项和外部扰动情况下的控制问题。结合自适应控制理论和滑模控制理论,通过选取一种具有较强鲁棒性的分数阶积分滑模面,设计自适应滑模控制器。该控制器可在参数不确定项、非线性不确定项和外部扰动的上界未知的情况下,实现局部渐进稳定。数值仿真结果验证了该控制器的有效性。

For the chaotic system with parameter-indeterminate fractional-order PMSM,the control problem with nonlinear uncertainties and external disturbances is studied.Based on the adaptive control theory and sliding mode control theory,an adaptive sliding model controller is designed by selecting a fractional-order integral sliding surface with strong robustness.The controller can achieve local asymptotic stability under the condition that the upper bounds of parameter uncertainties,nonlinear uncertainties and external disturbances are unknown...
