摘　　要：基于耗散性与稳定性之间的等价关系和投影原理,设计具有L2增益的非线性自适应鲁棒器应用于感应电机控制是一种新颖的方法。针对感应电机转子电阻与负载转矩的不确定性,在设计控制器时,引入与不确定性参数相对应的可调参数。利用投影定理设计了自适应控制律,在线修正参数值,同时耗散性分析中采用了L2增益算法,使系统不但对不确定项具有鲁棒性,而且对外部干扰具有抑制作用,保证整个闭环系统的动态品质。数值仿真验证了设计方法的正确性。Based on the equipollence relationship of passivity and stabilization and direct project theorem, an nonlinear adaptive L1-9ain robust controller was designed. It is a novel approach that the method is applied to the control of induction motor. Considering the uncertainty of rotor resistance and load torque, adjusted parameters corresponding to uncertain ones were introduced. According to direct project theorem, the adaptive control law was acquired by adjusting parameters on-line. Meanwhile the k gain algorithm was adpoted as passivity analysed. The designed control scheme ensures the total system is not only robust to rotor resistance and load torque, but also restrains exogenous disturbance. So the dynamic quality of closed loop system is guaranteed. The correctness of the design method was verified by a numerical simulation.
