| Abstract: | For the control problem of electronic throttle,which was the important component of electronic control system for automobile engine,the strategy of open-loop compensation and closed-loop control combination was proposed and was analyzed by simulation.Taking MC9S12X128 16-bit microcontroller as the main control chip,the hardware and software of electronic throttle control system were designed and the accurate control of electronic throttle based on torque was realized.The control function of the system was verified through the experiment.After further improvement,the system could meet the actual needs. |
