| Abstract: | In this paper,the generalized minimum variance is used for performance assessment of a thermal power unit control loop. The potential index and relative potential index are used to monitor the change of the closed-loop potential after tuning. The simulation results show that the generalized minimum variance can assess the performance of the thermal power unit control system well. |
