Automotive Electronic Throttle Simulation System Based on SystemVision

介绍了汽车电子节气门控制系统的组成及其工作原理。在SystemVision里面建立了电子节气门机械物理模型,在Matlab里面构建了电子节气门PID控制器。在SystemVision和Matlab平台上建立了电子节气门联合仿真系统。最后在联合仿真系统上进行了电子节气门PID控制算法的仿真实验,取得了对电子节气门的满意的控制效果,验证了联合仿真系统的有效性,为汽车电子控制系统的快速开发提供了一种行之有效的途径。

The constitution and working principles of electronic throttle control system were introduced.Electronic throttle body physical model was designed in SystemVision.By setting up the communication interface between SystemVision and Matlab,the automotive electronic throttle simulation system was constituted.A PID controller for an electronic throttle of an internal combustion engine was proposed to the simulation system.The result of simulation shows that the PID control strategy has been verified experimentally.And this system provides an effective solution to the rapid control for automotive electronic control system.
