Abstract

This chapter proposes two design procedures for fuzzy phase-lead compensator design based on frequency and transient characteristics. The main feature of fuzzy phase-lead compensator proposed in this chapter is its effective phase compensating characteristics. We derive two important theorems by introducing concept of frequency and transient characteristics. The first theorem is for judging whether a fuzzy phase-lead compensator should be used or not. The second is for realizing a phase-lead compensation. A design procedure (Design Procedure 1) of fuzzy phase-lead compensators for linear system is constructed using the theorem. Furthermore, it is extended to a design procedure (Design Procedure 2) for unknown or non-linear system. We apply Design Procedure 2 to tank level control problem which is a non-linear system with dead time. Simulation results show validity of these design procedures.
