摘　　要：针对永磁同步电机动态数学模型存在的问题,本文基于永磁同步电机非线性模型,利用有限时间的控制方法,对永磁同步电机的命令滤波位置跟踪控制进行研究,提高了系统的收敛速度及干扰抑制能力。在传统反步设计方法的基础上,引入命令滤波技术,克服了在传统反步控制中由于对虚拟控制函数连续求导引起的"计算爆炸"问题,通过设计补偿误差机制,减小了滤波误差,并利用Matlab仿真软件进行仿真验证。仿真结果表明,本文设计的控制方法能够克服负载扰动的影响,使跟踪误差收敛到原点一个充分小的邻域内,实现了对永磁同步电机准确快速的位置跟踪控制。该研究在实际工业过程中具有一定的实用意义。In view of the existing permanent magnet synchronous motor dynamic mathematical model,the permanent magnet synchronous motor control method based on nonlinear model,using finite time,in order to filter PMSM position tracking control research,improve the convergence speed and interference suppression ability of the system.Based on Backstepping in the traditional design method,introducing the command filter technology can successfully overcome the backstepping in the traditional control caused by continuous derivative in the'calculated explosion'problem,through the design error compensation mechanism,and reduce the filtering error.Finally,we use Matlab simulation software for simulation.The simulation results show that the design of the control method can overcome the influence of load disturbance,make the tracking error converge to a small neighborhood of the fully origin,finally realizes fast of permanent magnet synchronous motor position tracking control.The study has certain practical significance in the practical industrial process.
