5. Experimental Setup of the SRM Drive using Matlab Simulink The experimental setup is shown in Figures 5 and 6. Shows the GA-PID and ACO-PID controllers for a 3-phase 60KW SRM motor which are implemented & simulated by using Matlab-Simulink software program. Motor parameters used for simulation are given in Table 1. Tables 2 and 3 shows the GA-PID and ACO-PID controller’s parameters. the response of Kp, Ki and Kd parameters are summarized on table 4 which shows that the proportional controller “Kp” will have the effect of reducing rise time and will reduce the steady state error while the integral controller “Ki” will have the effect of eliminating the steady state error but will have the worst transient response on a system while the derivative
So changing one of them will lead to change the other two.

6. Simulation Results To explore the effectiveness of the proposed techniques, computer simulation has been carried out. The conventional PID, GA-PID and ACO-PID controllers were simulated using Matlab-Simulink software on a PC. In the simulation software package, operation of the entire system [i.e. the working of the voltage source inverter, switches operation, position of the rotor, reference and actual speed values, speed error and change in the error] can be observed.

Figure 8 shows the variable step input (Speed) and the motor actual output speed after using PID controller

Figure 9 shows the delay on the output of the motor with reference step input when using PID
