本文针对考虑边端效应的直线感应电机精确位置跟踪的问题,设计了一种基于间接矢量控制的投影自适应指令滤波反推控制器.首先,给出了间接矢量控制下考虑边端效应的直线感应电机模型;其次,运用反推法设计控制器,同时采用限幅的指令滤波器处理反推法中计算膨胀和控制器饱和问题,并对指令滤波器产生的滤波误差设计了补偿信号;然后,基于李雅普诺夫稳定性理论设计自适应律,估计直线感应电机控制系统中的不确定参数(移动物件的总质量、粘滞系数、外部的负载扰动),并引入投影算子保证估计值的有界性;最后,将所设计的控制器分别与传统PID控制器、指令滤波反推控制器对比,仿真结果表明,所设计的控制器具有更强的动态性能、抗干扰性及鲁棒性.
In this paper, aiming at the problem of precise position tracking of linear induction motor with edge effect, a projection adaptive command filter backstepping controller based on indirect vector control is designed.Firstly, a straight line considering edge effect under indirect vector control Induction motor model. Secondly, the controller is designed by using the backstepping method. At the same time, the limiter order filter is used to deal with the calculation of the expansion and controller saturation in the backstepping method, and the compensation signal is designed for the filter error caused by the instruction filter. , An adaptive law is designed based on the Lyapunov stability theory to estimate the uncertain parameters (total mass of moving objects, viscosity coefficient and external load disturbances) in the linear induction motor control system and to introduce the projection operator to ensure the estimated value Finally, the designed controller is compared with the traditional PID controller and the instruction filter backstepping controller. The simulation results show that the designed controller has more dynamic performance, anti-interference and robustness .
