Dongguan brushless dc motor manufacturers control of the brushless dc motor with position sensor and no position sensor and three kinds of intelligent control. the dongguan brushless dc motor manufacturer brand of small make up will explain the three control methods.
dongguan brushless dc motor manufacturers
one, with position sensor control with position sensor control is installed on the brushless dc motor stator position sensor to detect the rotor position and control of the stator winding commutation. Position sensor is used in the electromagnetic (Such as magnetic resistance rotating transformer), photoelectric (If the mask), magnetic susceptibility (Such as hall sensor)* is widely used, such as the hall sensors.
2, sensorless control of sensorless brushless dc motor control, not directly on the brushless dc motor stator installation position sensors to detect the rotor position. It usually use direct against potential detection, potential three harmonic method, the current path monitoring method, open circuit voltage method, the phase inductance method, the potential logic level methods such as integral comparison method to indirectly detect the rotor position.
3, intelligent control, intelligent control is the advanced stage of development of control theory, and generally includes fuzzy control, neural network control, expert system, etc. Intelligent control system has the function such as self-learning, adaptive, self-organizing, able to solve the problem of model uncertainty, nonlinear control, and other more complex problems. Dongguan strictly brushless dc motor manufacturer)0 is introduced, the BLDCM is a multi-variable, nonlinear, strong coupling, so using intelligent control can achieve satisfactory control result.
at present, there have been many more mature intelligent control methods applied in brushless dc motor control, for example: the combination of Fuzzy control and PID control Fuzzy -PID control, fuzzy control and neural network with the combination of compound control and the parameters of the membership degree by the genetic algorithm to optimize the fuzzy control and single neuron adaptive control, etc.
