| 摘 要： | 为了对某工程车辆半主动悬架的油气弹簧进行有效控制,分析了油气弹簧弹性力和阻尼力的非线性特性,建立了车辆半主动油气悬架非线性动力学模型.提出了应用微分几何理论并经过非线性状态反馈变换的方法,对半主动悬架非线性系统进行精确线性化,利用线性二次型调节器实现了非线性状态反馈最优控制,并用Matlab/Simulink编程进行仿真实验.仿真得出半主动油气悬架与被动油气悬架相比,显著地提高了车辆的平顺性.研究结果表明此方法可为车辆悬架控制的研究提供参考.

| Abstract: | In order to carry out an effective control for a core component of the semi-active suspension of an engineering vehicle,the nonlinear characteristics of the spring force and damping force of the hydro-pneumatic spring were analyzed and a nonlinear dynamics model for vehicle semi-active hydro-pneumatic suspension was established.The method of exact linearization to the nonlinear system of the semi-active suspension was proposed by applying the differential geometry theory and nonlinear state feedback transfo... |
