摘　　要：根据电子节气门控制系统的基本结构和工作原理,建立包含复位弹簧和摩擦等非线性特性的电子节气门非线性数学模型。针对电子节气门系统的非线性特性,提出电子节气门T-S模糊控制方法,以节气门开度偏差和偏差变化率作为模糊控制器的输入变量,以线性多项式的形式制定每条模糊规则的控制律,利用重心法计算得到T-S型模糊控制器的最终控制律。仿真结果表明该方法有较快的响应速度和较好的平稳性,对外界扰动具有一定的鲁棒性。According to the basic structure and working principle of the electronic throttle control system,a nonlin-ear mathematical model of the electronic throttle with nonlinear characteristics including the return spring and friction is established.Aiming at the nonlinear characteristics of the electronic throttle system,the electronic throttle T-S fuzzy control method is proposed.The throttle opening deviation and the deviation change rate are used as the input variables of the fuzzy controller,and the control law of each fuzzy rule is formulated in the form of linear polynomial,the final control law of the T-S fuzzy controller is obtained through the calculation by gravity method.The simulation results show that this method has faster response speed and better stability,and has certain robustness to external disturbances.
