Genetic optimization of a Type-2 fuzzy controller for output regulation of a servomechanism with backlash

A genetic-type-2 fuzzy logic controller (FLC) is proposed to achieve the output regulation of a servomechanism with backlash. The problem is the design of a type-2 FLC, which will be optimized by a genetic algorithm (GA) to obtain the closed-loop system in which the load of the driver is regulated to a desired position. The provided servomotor position is the only measurement available for feedback. Simulations results illustrate the effectiveness of the optimized closed-loop system.
