摘要
给出了一种无刷直流电机混沌系统的状态反馈控制方法。首先通过一个仿射变换和时间尺度变换,将转子磁场定向坐标系下的电动机模型变换成一种简单的无量纲模型。基于该模型,分析了无刷直流电机的混沌动态特性,最后采用Lyapunov稳定性方法,设计了一种状态反馈控制器,对无刷直流电机混沌系统进行控制,证明反馈控制系统是渐近稳定的。仿真结果验证了理论分析的正确性和控制方法的有效性。
A state feedback control method for the chaos system of brushless DC motors was proposed in this paper. Firstly, the model of brushless DC motors （BLDCM） in the rotor-field-oriented frame was transformed into the non-dimensional form via the affine transformation and the single time scale transformation. Then, based on the model, the chaos behaviors of BLDCM was analyzed. Finally, a state feedback controller, which was proved that it can drive the BLDCM chaos system to the steady state asymptotically, was designed by using the Lyapunov stability theory. Simulation results show that the theory analysis is correct and the proposed method is effective.
