Speed Control of DC Series Motor PV System via Improved Harmony Search Algorithm

Abstract

This article introduces the speed adjustment of the DC motor solar system. The developed design matter of the speed controller is established as an optimization problem. Improved Harmony Search Algorithm (IHSA) is employed to seek for optimum Proportional Integral (PI) parameters of speed controller by diminishing the time domain cost function. The performance of the suggested IHSA based speed control of DC motor has been contrasted with Particle Swarm Optimization (PSO) and the traditional PI controller found by Ziegler Nichols (ZN) under diverse operating cases and disturbances. The results of the suggested IHSA are confirmed via time domain analysis, and diverse performance indices. Simulation results have proven the influence of the developed approach in adjusting the speed of the DC motor over PSO and traditional algorithms.
