【摘要】 针对电液可变气门系统的升程控制,提出了基于支持向量机(SVM)的α阶逆系统控制模型。该方法适合高阶非线性系统的控制问题。根据系统的输入输出,离线建立变气门逆系统的辨识模型,然后将SVM逆系统串接在原系统之前,构成伪线性系统。仿真结果表明:基于SVM的α阶逆系统控制模型,对电液变气门系统的升程,表现出了良好的控制特性。更多还原

【Abstract】 The αth-order inverse system control model based on support vector machine(SVM)is proposed to realize lift control of electro-hydraulic variable valve system.The proposed method is suitable for the control problems of high order and non-linear systems.The off-line inverse system model of the electro-hydraulic variable valve system is established according to the system input and output.A pseudo-linear system is obtained after cascading the SVM inverse system before the original system.The simulation results show that good control characteristics of the VVS can be achieved by utilizing αth-order inverse system control model which is based on SVM.更多还原
