PI Control for Second Order Delay System with Tuning Parameter Optimization
نویسندگان
چکیده
In this paper, we consider the control of time delay system by Proportional-Integral (PI) controller. By Using the HermiteBiehler theorem, which is applicable to quasi-polynomials, we seek a stability region of the controller for first order delay systems. The essence of this work resides in the extension of this approach to second order delay system, in the determination of its stability region and the computation of the PI optimum parameters. We have used the genetic algorithms to lead the complexity of the optimization problem. Keywords—Genetic algorithm, Hermit-Biehler theorem, optimization, PI controller, second order delay system, stability region.
