摘要
以2自由度1/4车辆的悬架动力学模型为研究对象,提出滚动时域H∞输出反馈控制策略。利用在线最小化H∞性能指标,设计控制器,协调相互冲突的诸性能要求。仿真结果表明,系统在保证满足约束的前提下可以尽可能地降低干扰对输出的影响,获得优化的动态性能指标。
A LMI-based strategy of output feedback H∞ control combining moving horizon scheme is proposed for a quarter vehicle suspension model with 2 DOFs. The H∞ performance indicator is minimized online to compromise the conflicted requirements for obtaining the best overall performance of controller. Simulation results show that the system can minimize the possible effect of interference on output to get the optimized dynamic performance while meeting constraints imposed.
