摘　　要：针对感应电机由于其变量非线性耦合、电机参变性导致交流调速控制复杂,提出了一种基于微分几何理论的非线性自适应解耦控制方法。将自适应策略与输入输出解耦控制相结合,通过定义选择适当的Lyapunov函数来保证整个系统的稳定性,进而导出系统控制律及参数自适应律。系统可在电机参数变化和负载扰动的情况下,渐近跟踪参考模型给出的转速和磁链信号.仿真结果证实了该方法的有效性。The control of induction motor is a difficult problem as the nonlinearity of the dynamics and significant variation of the motor parameters,the nonlinear adaptive decoupling control was presented for the induction motor drive system based on differential geometry.Adaptive control was combined with input-output decoupling control in this paper.The stability of the drive system can be guaranteed by defining the virtual control and selecting the proper Lyapunov function,and the control law and parameter updating law were derived.The system can asymptotically track the rotor speed and flux reference signals generated by the reference model under parameter uncertainties and load torque disturbance.Simulation results show the validity of the nonlinear adaptive decoupling control strategies.
