ON INTEGRAL ACTION OF THE FUZZY CONTROLLER
Chao Xu · Acta Automatica Sinica · 1985
The problem of introducing integral term in a fuzzy controller to reduce steady state error is considered. It is pointed out that, in general, the error not be comple-tely eliminated by the fuzzy controller even integral action is applied; however, the error can be made so small by the controller as to be accepted in applications. A me-thod of integrating the “fuzzy value”of the error signal to take care of both dynamic and steady performances is proposed, which is proved reasonable by digital simulation.
