Using Genetic Algorithm for the PID Control of Voice Coil Actuator in A Precision Locating System and Simulation

Abstract

Precision manufacturing is very important in the modern industrial manufacturing. Voice coil actuator (VCA) is the actuator, which directly change the signal of electricity to movement. We devised a form of precision locating system driven directly by VCA and apply gas static pressure bracing to substitute rigid bracing by mechanical contact. PID Control is widely used to control the system, but the parameters of PID control hard to be get out. Genetic algorithm is imitate living creature environment in of a kind of orientation overall situation of the genetic, can be professional at solving complicated system or the huge problem and it acquired a success application in many industrial engineering realms and had already got extensive concern. Thus, we use genetic algorithm to find the right parameters of PID control. As a whole, in this paper we introduce the genetic algorithm, analyze the control model of precision locating System, discuss using the Genetic algorithm to find the right parameter to control the precision locating System of voice coil actuator, the simulation is give out.
