摘要：

A systematic procedure for performance assessment and PI/PID controller design based on modified relay feedback test is proposed in this paper. It can estimate the gain and phase margins of unknown systems on-line to indicate the appropriateness of the controller parameters. When the retuning of controller is found necessary, the proposed modified relay feedback scheme can be applied to tune the PI/PID controller based on specifications of gain and phase margins. Performance assessment and controller design can be done simultaneously, which ensures a good performance of the control system.
