Research On The Online Closed-Loop Identification And Performance Assessment Of Control System

This dissertation mainly discusses the application of online closed-loop identification and performance assessment of control system on the spot. In the applied viewpoints, theory research, emulation experiment, application on the spot and software produce and so on, which is involved in application of online closed-loop identification and performance assessment in the thermal control system of the power plant are discussed. In the first, the identification method, identification theory, emulation experiment and problem involved in the identification are discussed based on theory and emulation, emulation with MATLAB proves the practicability; Then the contents of the "on-line closed-loop identification and performance assessment"particularly are described. Theses contents include software development, system's functions and the applications on the spot. Next, introduce the method of performance assessment based on minimum variance controller and setpoint response data.
