摘要
本文针对直流电机非线性系统提出了一种基于反向步进的非线性自适应速度控制策略。首先通过状态重构将直流电机系统模型转化为级联结构,其次考虑参数不确定及转矩干扰设计具有鲁棒性的自适应反向步进控制器。仿真结果表明本文提出的这种控制方法适用于参数不确定情况下的直流电机系统的速度调节且具有较好的速度跟踪性能。
A nonlinear adaptive speed control scheme based on back - stepping control technique is proposed for DC motor system. First state reconstruction techniques are used to transform the DC motor model into a cascaded structure and, then, nonlinear adaptive back - stepping controller is designed which is robust to the parameter uncertainties and load torque disturbance. Simulation results show that the proposed control scheme updates the system parameters and provides, under the condition of parameter uncertainties and load torque disturbance, an efficient control design both for speed tracking and regulation successfully.
