摘要
针对弹性负载情况下的电液力伺服系统非线性的问题,首先,以车用板簧力伺服系统为研究对象,对电液力伺服系统进行控制系统设计;其次,选择一阶参考模型跟随自适应控制算法作为控制策略对系统进行Simulink仿真分析;最后,对板簧进行力伺服控制实验.结果表明,电液力伺服系统力输出波形失真问题得到改善,取得良好的控制效果.该方法对模外动态和外加干扰都不敏感,可以抑制不确定性因素对系统的影响,具有较高的动态跟踪性能.
The electro hydraulic servo system with elastic load hasa nonlinear problem. To solve the problem, firstly, laminated spring force servo control system was taken as the object of study,the control system of electro-hydraulic force servo control system was designed. Secondly, with first-order reference model algorithms taking as control strategy, Simulation analysis of the system was carried out. Finally, spring force servo control system was tested. This method is insensitive to the external dynamics and the external interference, the influence of the uncertainties on the system can be restrained, and it has high dynamic tracking performance.
