- Abstract
PMSM is widely used in servo-drive applications because of its advantages such as high efficiency, high power density and torque/inertia ratio and maintenance free. In a permanent magnet synchronous motor, the dc field winding of the rotor is replaced by a permanent magnet. The advantages are elimination of field copper loss, higher power density, lower rotor inertia and more robust construction of the rotor. The PMSM has higher efficiency than an induction motor, but generally its cost is higher, which makes the life cycle cost of the drive somewhat lower. In this paper, the speed control (tracking) of PMSM is achieved through PID controller. On-line tuning of PID controller parameters is done with the help of popular bio inspired optimization techniques such as PSO, Bat and Firefly algorithms based on most effective objective function Integral Time Absolute Error (ITAE). Obtained results are presented in tabular as well as graphical form for better understanding.
