Abstract

The invention relates to a control system and a control method of a three-phase brushless direct current motor. The control system comprises a processing chip, the processing chip comprises a processing system and a programmable logic, and the processing system is connected with the programmable logic through a high-speed communication interface; the signal acquisition chip acquires a set electricsignal of the three-phase brushless direct current motor; the programmable logic generates a first interrupt and transmits a set electric signal to the processing system according to the first interrupt, and generates a second interrupt; the processing system performs a setting algorithm on the set electric signal according to the second interrupt so as to generate a pulse width modulation signalto the programmable logic; the programmable logic analyzes the pulse width modulation signal; and the driving chip controls the three-phase brushless direct current motor according to the analyzed pulse width modulation signal. Through the technical scheme of the invention, the function expansion of the control system and the integration of multiple functions are facilitated, so that the controlsystem of the three-phase brushless direct current motor has better compatibility and higher integration level.

Description

technical field [0001] The present disclosure relates to the field of motor technology, in particular to a control system and a control method for a three-phase brushless DC motor. Background technique [0002] In view of the control requirements of three-phase brushless DC (BLDC, Brushless Direct Current) motors, which require high real-time performance and high reliability, the control process of three-phase brushless DC motors has extremely high requirements on the performance of the main processor, such as interrupt performance. strict. In the existing three-phase brushless DC motor control scheme, the STM32 embedded microcontroller or DSP (Digital Signal Processing, digital signal processing) chip developed by STMicroelectronics is generally used as the main processor to control the three Phase brushless DC motor work. [0003] However, the STM32 embedded single-chip microcomputer or DSP chip has limited peripheral function interfaces. In the process of controlling th...
