英文摘要

      The estimation of process parameters and process time delay can be achieved simultaneonsly by applying a general model and a general prediction theory. On this basis, an optimal prediction algorithm of self-tuning pole assignment PID controller that overcomes time-varying fractional delay is presented in this paper. Computer simulation shows that the proposed algorithm possesses better robustness. Using this algorithm, the influence of time-varying parameters and fractional time delay can be reduced.
