A Performance Analysis of Brushless DC Motor by using PID Controller

Increase in need of industry for high productivity is placing new demands on mechanisms connected with electrical motors. This leads different problems in operation due to fast dynamics and instability. The stability of the system is essential to work at desired set targets. The non- linear effects caused by a motor frequently reduce stability, which reduces the controllers ability to maintain speed or position at set points. Hence number of the industrial process applications requires speed& position control of DC motor. A brushless DC motor described as magnet being the rotor and its stationary windings forming the stator. This design provides many advantages over the brush DC motor. Brushless DC (BLDC) motor drives are becoming widely used in various consumer and industrial systems, such as servo motor drives, home appliances, computer peripherals, and automotive applications in recent years because of their high efficiency, silent operation, compact form, reliability, and low maintenance.
