PWM系统的宏观控制性能研究

摘要

对PWM控制系统进行了运动分析,定义了反映PWM控制系统的宏观控制性能的λ线,对采用状态反馈和输出反馈改善PWM控制系统的宏观控制性能进行了研究,用MATLAB进行了仿真,验证了所提出方法的有效性.%The paper analyses motion of the PWM control system by means of modern control theory, defines the A line that can reflect the macro-control performance of PWM control system, and researches the macro-control performance of PWM control system by the state feedback and output feedback. The result shows by MATLAB that the method raised by the paper is valid.
