Identification and PSO-PI based position control for a practical DC Servo System

The aim of this paper is to design a position controller of a practical DCmotor by selection of a PID parameters using the PSO algorithm. The model of the DCmotor is identified as a seventh order system. This paper identifies the model andcompares two tuning methods for parameters of the PID controller. At first, thecoefficients have been tuned by PID Tuning Toolbox, and then the controller has beendesigned by the PSO algorithm. It was found that the proposed PID parametersadjustment by the PSO algorithm is better than the existing PID Tuning toolboxmethod.
