Abstract:

Research on hardware structure and control methods of simulated double-pointer barometer drive control system presently used in train driving simulation platform has been carried out. Pointer motor drive system has been designed using C8051F410 MCU and dual motor drive module BA6239 as system core, taking methods of PWM control technology, a close-loop motor speed control strategy has been proposed. System can automatically calculate motor control model parameters to obtain relationship between speed and PWM control voltage, and via bringing in adaptive fuzzy PI ASR, system and calculation errors have been minimized, and its dynamic response accuracy increases. Test results show that simulated double-pointer barometer based on adaptive fuzzy control can match with actual train barometer’s motion requirements, and it can provide reliable hardware support for building up train driving simulation platform.
