| 摘 要： | 1 .INTRODUCTIONFuzzy control has attracted considerable researchinterest from different communities , since fuzzysets were first introduced to the steamengine con-trol by Mamdani in 1974 . Avariety of applicationshave demonstrated that fuzzy control can provide abetter performance than the conventional PID con-trollers in dealing withill-defined systems .

| Abstract: | The analytical structures and the correspondin g mathematical properties of the one dimensional and two dimensional fuzzy control lers are first investigated in detail. The nature of these two kinds of fuzzy co ntrollers is next probed from the perspective of control engineering. For the on e dimensional fuzzy controller, it is concluded that this controller is a combin ation of a saturation element and a nonlinear proportional controller, and the s ystem that employs the one dimensional fuzzy controller is the combination of an open-loop control system and a closed-loop control system. For the latter cas e, it is concluded that it is a hybrid controller, which comprises the saturatio n part, zero-output part, nonlinear derivative part, nonlinear proportional par t, as well as nonlinear proportional-derivative part, and the two dimensional f uzzy controller-based control system is a loop-varying system with varying num ber of control loops. |
