摘　　要：为了解决永磁同步电机的非线性、强耦合及不确定干扰等因素的影响,文章拟采用非线性动态逆控制和反推控制相结合的方法来设计控制系统。动态逆控制能够实现多输入多输出系统的精确线性化,解决电机多变量间的强耦合问题。反推控制能够保证系统全局一致渐近稳定,但对变化较快和较大的参数扰动抑制不够理想,在此基础上,采用模糊参数逼近器来消除负载扰动等因素对电机的影响。仿真结果证明了该方法的有效性。In order to solve the influence of the permanent magnet synchronous motor nonlinear, strong coupling and uncertain disturbance, this paper is intended to apply the method of combing the nonlinear dynamic inversion control and backstepping control to design the control system. The MIMO strongly coupled system is accurately linearized using the dynamic inversion technique which can solve the problem of the motor ＂s multivariate and strong coupling. The backstepping control law guarantees the system global stability, but it can not attenuate the effects well for the changing faster and larger parameters. On the basis, the fuzzy parameter approximation based on fuzzy basis function vector is used to eliminate the effect of the disturbance. The efficiency of the proposed control scheme is verified using computer simulation.
