Abstract

Performance assessment is important for control parameter optimizing and control quality improvement. So an algorithm for the system performance assessment is proposed. Firstly, time scale choosing method is given in minimum variance algorithm which based on the Laguerre model for systems with stochastic disturbance only. Then for set point tracking systems with stochastic disturbance, calculation method of the tracking time is proposed, by which sampling data are divided into two parts, respectively used to get determined and stochastic performance index. Finally, detailed procedure of comprehensive assessment is given. Simulation proved the effectiveness of the algorithm.
