β¦ Synopsis
A fuzzy logic controller (FLC) designed as a suction controller is proposed. Firstly, we prove that there exists a switching line in the FLC, and the slope of the switching line is determined by scaling factors. Secondly, a Lyapunov function is selected and sufficient conditions for the fuzzy control system (FCS) to be globally asymptotically stable is determined. Based on the sufficient conditions, a design procedure is suggested to guarantee that the FCS is globally asymptotically stable. Both a nonlinear oscillator and a cart-pole system are simulated to demonstrate the proposed FLC. We show that not only is the FLC similar to sliding mode control (SMC), but also a realizable method for a suction controller is described. In addition, a lemma is introduced to interpret that the rise time &the FCS can be adjusted by the scaling factors. @

Controller design is considered for system specifications which are not handled naturally by analytical methods. Using fuzzy sets and related theory, system specifications are translated into preference functions which are readily combined with search methods to determine adequate controller paramet
We suggest a simple but powerful FLC (Fuzzy Logic Controller) design method using a single fuzzy input variable, which is equivalent to the pseudo sliding mode controller. Input variables of conventional FLCs are mostly the error e and the change-of-error ~ regardless of the complexity of controlled
