中文摘要：
为提高系统可靠性,改善系统故障情况下的容错控制效果,推导出系统传感器和执行器两类故障的统一数学模型,同时考虑控制对象的不确定性,基于Lyapunov渐近稳定性理论和Riccati方程研究鲁棒容错控制器设计方法,设计基于状态观测器的船舶航向/横摇鲁棒容错控制器,并对其进行仿真检验.结果证实了该方法的有效性.
英文摘要：
To enhance system reliability,while improving the effect of system fault-tolerant control under fault conditions,unified mathematical model of the system sensor and the actuator was given.The uncertainty of control object was considered simultaneously.Based on the Lyapunov asymptotic stability theory and the Riccati equation,the robust fault-tolerant controller design method was studied,and ships course/roll robust fault-tolerant controller based on the state observer was designed.Simulation test results confirm the validity of the proposed method.
