The objective of this paper is to build a speed control technique for brushless DC (BLDC) machine, study the performance of the same motor under different speed and load torque conditions and finally to analyze the stability of the BLDC motor by using different stability criterion. Here a soft computing technique PSIM is used for the simulation of the BLDC motor and the PID controller has been developed in MATLAB which is then linked with PSIM using the SIMCOUPLER for controlling the generation of the variable gate pulse for the voltage source inverter (VSI).The simulation results of BLDC motor performance shows that it gives good results of speed control which can critically evaluated under various input parameters in the PSIM environment. The accuracy of this approach can also be verified by comparing the simulation results in PSIM with the results of the response obtained from the BLDC motor.
