电子节气门控制系统具有强非线性时变特性,需采用非线性控制方法进行控制,其中滑模控制应用比较普遍,但系统在切换状态时容易出现抖振现象,不利于系统的精确控制.为改善性能,采用模糊自适应调节滑模控制方法,用模糊逻辑系统来代替传统滑模控制中的指数趋近率系数,从而达到消除滑模控制抖振现象.根据系统数学模型设计了模糊自适应调节滑模控制器,通过在Matlab中进行仿真.仿真结果表明:模糊自适应调节滑模控制能有效解决系统存在的非线性问题,消除滑模控制中出现的抖振,满足系统精确控制的要求.

Electronic throttle control system has strong nonlinear time-varying characteristics,it must be controlled by nonlinear control method,in which the sliding mode control is used more common,but it is prone to appear vibration,which is not conducive to the precise controlling in the system.In view of this situation by using the fuzzy adaptive adjustment sliding mode control,in which the fuzzy logic system replaces the coefficient of index closer rating in traditional sliding mode control,ao as to eliminate the vibration.According to the mathematical model of the system the fuzzy adaptive adjustment sliding mode controller is designed,and simulate it in MatLab.The simulation results indicate that the designed controller can effectively solve the nonlinearity problem,and Can eliminate the vibration in the sliding mode control,and meet the requirements of precise controlling of the system.
