摘要: 结合命令滤波和神经网络技术设计了永磁同步电机离散位置跟踪控制方法。使用欧拉公式建立永磁同步电机离散模型,用神经网络技术来逼近非线性函数,应用命令滤波技术解决传统反步法中的“计算复杂性”问题,引入补偿机制成功地解决滤波误差问题。仿真结果表明,该控制器有良好的位置跟踪性能,能够解决输入饱和的影响,且对外部负载扰动有较强的鲁棒性。

Abstract: In this paper, a discrete-time position tracking control method for permanent magnet synchronous motor (PMSM) was designed by combining command filtered control and neural network technology.The continuous dynamic model of PMSM drive systems was transformed into discrete-time form by using Euler formula. The nonlinear function was approximated by applying neural network technology in the process of controller design.The application of command filtered control technology could solve the “complexity of computation” problem in the traditional backstepping method, and the introduction of a compensation mechanism successfully solved the problem of filtering error.The simulation results showed that the designed controller had good position tracking performance, could solve the influence of input saturation, and had strong robustness to external load disturbances.

Key words: permanent magnet synchronous motor (PMSM), input saturation, discrete-time, command filtered control, neural network
