Multi-model Adaptive Internal Model Control and Application

Considering the characteristics of time delay,time-variables,uncertainties and non-linear in process control system,multi-model adaptive internal model control(MMA-IMC) was constructed on the basis of traditional internal model control(IMC) in this paper.Simulation result of given plant showed that the proposed MMA-IMC design method is superior to its conventional counterpart and PID in performance of stability and robustness and response speed.
