本文提出了一种基于波形分析和专家系统技术的专家控制方法。本方法通过分析闭环系统在阶跃负载扰动作用下输出波形的特征值,即振幅衰减比及振荡周期,自动地进行控制策略的选择和调节器参数的整定。
This paper presents an expert control method based on waveform analysis and expert system technology. This method automatically selects the control strategy and adjusts the regulator parameters by analyzing the eigenvalues of the output waveform of the closed-loop system under step-load disturbance, that is, the amplitude attenuation ratio and the oscillation period.
