| Abstract: | Simultaneous estimation of process parameters and process time delay can be achieved by applying a general model. Based on this model ,an algorithm of the pole assignment optimal prediction self-tuning PID contrller which adapts to the process with unknow or time-varying fractional delay is proposed in this paper. The algorithm has not only PID control features, but also self-tuning control and optimal prediction features that may overcome the time delay. Simulation results indicate that the general model algorithm are very effective in on-line identification and control for time-varying fractional delay systems. |
