Abstract

The system and method for controlling electrical motor with no position sensor and brushless are based on angle self-learned, and switching self-optimized optimized efficiency. The system is composed of power supply circuit, power drive circuit unit, DSP control circuit, detection circuit unit for rotor position, voltage detection unit, current detection unit, and temperature detection unit etc. The software part includes following modules: initialization module, external synchronization starting up module, module for switching external synchronization to self - synchronization, self adaptive raising speed module for self - synchronization, hardware module for computing signal of position, and module for optimizing operating efficiency. The disclosed driving controller makes motor with no position sensor and brushless start up smoothly and operate in high efficiency under large dynamic load range. Including CAN comm interface, the system guarantees reliable comm to bus of vehicle.

Description

technical field [0001] The invention relates to related technical fields related to the drive and control of compressor loads, and proposes a positionless brushless motor control circuit based on self-learning optimization and its control method, especially a new type of electric drive control system for vehicle air-conditioning compressors and methods. Background technique [0002] With the rapid development of high-performance permanent magnet materials, microelectronics technology, automatic control technology and power electronics technology, especially high-power semiconductor devices, permanent magnet synchronous motors have developed rapidly. Because of its superior speed regulation performance, small size, light weight, high efficiency, small moment of inertia, and no excitation loss problem, it has broad application prospects in various fields. Permanent magnet synchronous motors can be divided into permanent magnet synchronous motors (PMSM) with sine wave back ele...
