Abstract

The problem is the design of 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. This problem is solved by extending the Fuzzy Lyapunov System to the design of Type-2 Fuzzy Controllers for a servomechanism with nonlinear backlash. The servomotor position is the only measurement available for feedback; the proposed extension is far from trivial because of nonminimum phase properties of the system. Performance issues of the Type-2 Fuzzy Regulator designed are illustrated in a simulation study.
