摘　　要：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.An example is included to verify the effectiveness of the controller.
