Abstract
This paper addresses the analysis and design of an observer in order to ease the difficulty of working with various variables for the design of type-1 fuzzy controllers. In this paper Fuzzy Lyapunov Synthesis, based on the observed system, is extended to the design of type-1 fuzzy logic controllers for nonsmooth mechanical systems. The output regulation problem for a servomechanism with nonlinear backlash is proposed as a case of study. The problem at hand is to design a feedback controller so as to obtain the closed-loop system in which all trajectories are bounded and the load of the driver is regulated to a desired position while also attenuating the influence of external disturbances. The servomotor position is the only measurement available for feedback; the proposed extension is far from trivial because of the nonminimum phase properties of the system.
