【Abstract】 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.更多还原
