摘　　要：文章先对电子节气门控制系统的基本结构、工作原理以及非线性因素进行了简要分析,并建立了系统的数学模型。选择PID的控制策略,通过Matlab/Simulink平台对电子节气门控制系统进行建模仿真。仿真曲线说明使用PID策略当控制目标变化时,呈现超调、反应时间长、稳定时间久的态势。但其结构相对简单,较容易实现,可与其他现代控制方法相结合改善。This article firstly analyses the basic principle and structure and of the electronic throttle control system. And then it analyses non-linear factors of systems and establish the mathematical model of the system. I select PID control strategy, and establish the electronic throttle control system simulation models in Matlab/Simulink. Simulation result shows overshooting, longer response time and longer time to be stable, when using PID control strategy to control. But its structure is simple, and is easy to implement. This strategy also can be combined with other modem control methods for improvements.
