RESEARCH ON SELF-ADAPTIVE FUZZY CONTROLLER FOR TIME-DELAY SYSTEM

Combined with Smith pre estimation controller and the internal model controller ,this article presents a self-adaptive intelligent controller which can get better controlling performance within some range of model error with fuzzy method. The main control input comes from the fuzzy controller, at the same time, gets rid of the state error through intelligent integrator. Furthermore, it can adjust model errors by addition of a fuzzy adjuster through monitoring the system performance.
