Tips: Control Methods of DC Brushless Motor
DC brushless motor has three control methods, namely position sensor control, sensor-less control and intelligent control.

1. Position sensor control
Position sensor control detects the rotor position and controls the commutation of stator winding by installing position sensors on the DC brushless motor. The position sensors applied include electromagnetic type (such as reluctance resolver), photoelectric type (such as light screen) and magnetic type (such as hall sensor). Among them, hall sensor is the most widely applied.
2. Sensor-less control
Sensor-less control doesn't detect the rotor position by directly installing position sensors on the DC brushless motor. Generally, it detects the rotor position through direct back EMF detection method, back EMF three harmonic method, current path monitoring method, open-circuit phase voltage detection method, phase inductance method and back EMF logic level integration comparison method.
3. Intelligent control
Intelligent control system has the functions of self-learning, self-adapting and self-organizing, it can solve the problem of model uncertainty, nonlinear control and other complicated problems. At present, many mature intelligent control methods have been applied to the control of Brushless DC motor, such as the Fuzzy-PID control combined by fuzzy control and PID control, compound control based on fuzzy control and neural network, fuzzy control of membership parameters optimized by genetic algorithm, mononeuron adaptive control.
