Evolutionary algorithms based controller design for industrial applications

Abstract

A controller is a device which monitors and affects the operational newlineconditions of a dynamic system In process industries most of the problems newlineare multivariable in nature The controller has the adjustable parameters newlinewhich should be tuned properly to achieve required steady state and transient newlinestate performances The tuning of controller for the multivariable system is newlinereally challenging due to the interactions among the variables Various control newlinestrategy like optimal control robust control intelligent control adaptive newlinecontrol and stochastic control has been successfully implemented in industrial newlineapplications Inspite of this more than 90 of the industrial controllers are newlinebased on the ProportionalIntegralDerivative PID controllers The reason newlinefor the wide popularity of PID controller is for the simplicity clear newlinefunctionality applicability and robustness in nature newline newline
