PSO Based Design of Current CCII-PID Controller for the Speed Control of BLDC Motor

A conventional DC motor has remained the area of interest for a wide range of applications. With the invention of BLDC motor which has many advantages over conventional DC motor, it has found it application in almost all the application by replacing conventional DC motor. Here, in this paper, we analyze the performance of BLDC motor using PID controller. To design the PID controller we have used Particle Swarm Optimization (PSO) based algorithm. The seminal work of this paper is to realize the controller circuit using only one second generation Current Conveyer (CCII) circuit. The performance has been validated using simulation with handy CCII IC AD844 in Multisim. Since, the transient behavior of a motor is of main concern, so this will be worthy to mention that the paper gives results in time domain. Moreover, the paper is not restricted up to only transient response, however, it also gives various steady state parameter like error in the output when transient dies out which is usually considered after 5τ sec in the literature.
