BLDC motor field orientation control system based on LPIDBP neural network

Abstract

In order to improve the performance of BLDC motor system , a brushless direct current (BLDC) motor FOC control system based on LPIDBP neural network is designed in this paper, which combining LPIDBP neural network with field orientation control (FOC) strategy. The control strategy and implementation method are put forward, and the system simulation model is established. The simulation results show the control performance of designed BLDC motor FOC control system is good, the torque ripple and speed ripple is small. STM32F103B is used as the main control chip to design the BLDC motor FOC control system test platform, and a BLDC motor monitoring system is designed by VB(Visual Basic). The contrast testing speed curves from monitoring system show the best performance of BLDC motor FOC control system based on LPIDBP neural network ,the system response is the fastest, the speed ripple is the smallest, and the operation is the stablest.
