具有参数乘性摄动系统的鲁棒完整性研究

Robust Integrity in Systems with Multiplicative Perturbations on Parameters

针对 [0 ,σ](σ )故障模型 ,讨论了具有参数乘性摄动的系统存在执行器故障、传感器故障及执行器和传感器同时发生故障时具有鲁棒完整性的必要条件和充分条件 ,并应用H∞ 控制理论 ,给出了鲁棒容错输出反馈控制器的设计方法。

In this paper, based on the failure model in which the elements of failure matrix take values between 0 and , sufficient conditions and necessary conditions for robust integrity are proposed respectively for systems with multiplicative disturbances on parameters when failures on actuators, sensors or both occur. An output feedback robust fault tolerant control method is demonstrated by setting the equivalent relation between the conditions and the general H ∞control problem.
