Abstract :
An intelligent fuzzy controller is designed for the controlled objects which have the characteristics of time-delay nonlinear and variable parameters. The controller is composed of mindlike intelligent integral and two-dimensional fuzzy control. A regulating device is proposed for the valves that are always out of control. The device has the structure of a double-loop cascade control system and can realize intelligent switching. A number of simulations and practical applications show that the intelligent switch and intelligent fuzzy cascade reheated steam temperature control system which are configured and realized by using the CLC-04 programmable regulator have better controllability, anti-jamming, and robustness than that of a PID cascade system and a robust state-feedback cascade system
