Abstract

The invention discloses an adaptive control method based on the calculation of the advance angle of an inductive brushless motor. When the motor is working at a set speed and power, an automatic calculation software module with a calculation formula of the advance angle in the motor controller is activated, Fine-tune the advance angle and record the relevant data; after the motor runs for a period of time, after the range of fine-tuning of the advance angle reaches the set range, compare all the motor operating efficiency data during the fine-tuning process to obtain the advance angle corresponding to the highest operating efficiency The calculation formula of the advance angle is revised, and the relevant parameters of the revised calculation formula of the advance angle are stored in a readable and rewritable memory, so as to be recalled in the later running of the motor. It saves a lot of resources and time, and the obtained advance angle calculation formula can be determined as the best advance angle formula of the motor under this condition, which improves the motor efficiency and increases the product competitiveness.

Description

technical field [0001] The present invention relates to an adaptive control method based on the calculation of the advance angle of an inductive brushless motor. Background technique [0002] BLDC motor is widely used in various electrical equipment due to its energy saving, environmental protection and high controllability. There are currently two control methods for brushless DC motors. Brush motor (using scalar control technology); the other is to detect the phase current of the coil winding to obtain the rotor position, that is, a brushless motor without position sensing, usually vector control technology is used to transform the phase current of the motor for coordinate transformation. Vector control, the current Id and Iq on the rotor coordinate system are obtained, and the weak magnetic speed regulation is realized by adjusting the value of Id. The implementation of this method is complicated, the operation is cumbersome, and it takes up a lot of computing resources o...
