Abstract :
For large time-delay plant, the algorithm of hybrid control algorithm of gray fuzzy is presented. The dynamic response of system is divided into several areas based on both current error and the change rate of error, and the different predictive length is given for different area. The output of fuzzy controller dependents on the sum of current error and predictive error. The algorithm synthesizes both the advantages of traditional fuzzy control and gray predication control. Simulation result shows that the control algorithm is very effective even for large time- delay plant.
