Displacement Control of Photostrictive Actuators for Vibration Control with the Aid of Fuzzy Logic Control along with PSO Algorithm

Abstract

Vibration in industrial equipment can be continuously monitored for unusual types of operating conditions and the resultant potential failures. Photo restrictive materials, exhibiting light-induced strains, are of interest for future generation wireless remote control photo-actuators, micro-actuators, and micro-sensors applications that exhibit large photo restriction under uniform illumination of ultraviolet light. In our proposed method, we are using fuzzy logic to illustrate the light intensity based on which the distance between the two modes is reduced using Particle Swarm Optimization (PSO) algorithm in such a way as to provide a lesser vibration result. In our proposed technique, the input is used as the velocity of the source and the displacement of the modes, the corresponding output being the light intensity. The optimal light intensity is chosen based on the displacement by means of which the corresponding displacement is again optimized to an extent desired using PSO algorithm to get further reduced vibration in the output. The accuracy of the PSO is done by comparing the result with normalized value and with the Genetic Algorithm and has proved that our proposed method produces optimal result. Thus our proposed method is projected to increase the efficiency in the output with a significant reduction in displacement.
