摘　　要：分别用传统PID和滑模变结构两种控制算法对电子节气门控制器进行软件设计,首先在Matlab/Simu-link环境下构建电子节气门结构体和控制器模型,并进行仿真,对控制参数进行优化获得最佳控制效果,然后使用自动代码生成工具Targetlink,将模型中控制器模块转化为C代码,并进行软件在环仿真,最后配置硬件I/O接口,将代码下载到硬件中进行测试试验。两者试验结果对比说明,传统PID控制节气门模型参数时变系统存在一定的局限性,而滑模变结构控制系统具有良好的鲁棒性,能快速、准确控制节气门开度。The software of electronic throttle controller was designed with traditional PID and sliding mode variable structure control algorithms.The structure body and controller model of electronic throttle were built and simulated under the environment of Matlab/Simulink and the optimal control effect was acquired by optimizing the control parameters.Then with Targetlink code generation tool,the control module was compiled into C code,which was simulated in the software-in-loop.Finally the code was downloaded to the hardware and tested through configuring the hardware I/O.The result shows that,compared with the traditional PID,the sliding mode variable structure has better robustness and can control the opening of throttle fast and accurately.The traditional PID has some limitations in controlling throttle model parameter time-varying system.
