中文摘要
      为了实现磁流变阻尼器(MRD)的高精度阻尼力跟踪控制,本文提出了一种基于Koopman算子的离散时间 线性二次型最优跟踪(DLQT)控制策略.采用递归神经网络(RNN)建立MRD的非线性模型.采取Koopman算子理论 及扩展动态模式分解法(EDMD)将MRD的RNN模型“全局”线性化,保留MRD系统的非线性特性.利用基于Koop man算子理论得到的高阶线性模型设计了DLQT控制器.通过仿真实验实现对不同频率的期望信号进行跟踪,验证 了算法的有效性.采用搭载了MRD的二自由度四分之一悬架实验台进行硬件在环实验.实验结果表明该算法可以 实现对参考信号的高精度跟踪.
英文摘要
      In order to realize a high-precision damping force tracking of magnetorheological damper (MRD), a discrete time linear quadratic tracking (DLQT) control strategy based on Koopman operators is proposed. Aiming at the hysteresis nonlinearity of MRD, a nonlinear recurrent neural network (RNN) model of MRD is established. Koopman operators the ory and extended dynamic mode decomposition (EDMD) algorithm are used to obtain a high-dimensional model of MRD. Adiscrete-time linear quadratic tracking controller is designed by using the high-dimensional linear model. The expected signals of different frequencies are tracked through simulation experiments, which verifies the effectiveness of the pro posed scheme. Furthermore, physics experiments are conducted on a 2-degree-of-freedom quarter suspension experimental system equipped with a MRD, which show that the strategy can achieve high-precision tracking of signals.
