摘要
针对永磁同步电机(PMSM)绕组相电流和转速强耦合特性以及参数的不确定性,利用非线性积分反步法设计了自适应积分反步控制器,在补偿参数不确定性影响的同时,实现了PMSM高性能位置跟踪控制.基于Matlab建立了系统的仿真模型并实施仿真.仿真结果表明,用该方法设计的PMSM控制系统,滤波跟踪误差能以指数规律迅速收敛到零,并且具有很强的抗负载扰动能力.
To compensate the parametric uncertainty and to realize the global asymptotic position tracking, an adaptive controller based on the integrator backstepping method is designed. Then the simulation model of the permanent magnet synchronous motor control system is established using Matlab and simulation is carried out. The results show that the filter position tracking error of the system adopting the designed controller converge to zero exponentially fast, and that this system is robust to the load disturbances.
