摘要
针对飞行控制系统中存在的多种不确定性,提出了飞行控制系统的多目标非脆弱鲁棒控制器的控制方法。由系统的H2性能、H∞性能、区域极点配置和保性能控制四种控制目标,用线性矩阵不等式(LMI)法导出多目标鲁棒状态反馈控制器的存在条件,同时考虑了飞行控制系统中控制器增益的加性摄动,设计的控制器实现了系统的四种性能指标优化。仿真实验结果表明:该控制方法有较强的鲁棒性。
According to the multiply uncertainness in the flight control system, the multi-object non-fragile robust controller was proposed in this paper. From the four control objectives that were H2 performance, H∞ performance, regional pole placement and robust guaranteed cost control, the existing conditions of the multi-object robustness state feedback controller were deduced by linear matrix inequality (LMI) approach. Also, the designed controller optimized the four performances were realized when the gain variation of controller in fight control system was in consideration. The simulation results showed that this method had strong robustness.
