摘要 控制系统的闭环特性在频域中是以幅值裕量和相位裕量表征的,由于被控系统在实际运行中工况条件存在不确定性,系统的性能往往达不到设计要求.提出一种基于继电反馈测试的方法,在线测量实时控制系统的两个频域指标,并在此基础上进行PI控制器的参数调整,以保持系统的闭环性能.仿真结果表明,该方法是有效的. Gain and phase margins are used as performance measurements in frequency domain. Due to the uncertainty of process, the desired performance always can not be achieved. A relay feedback test approach was proposed to estimate the system's two measurements of frequency domain. And PI controller parameters were tuned to retain the closed-loop performance. The simulation results show the validity of this method.
