【Abstract】 For a class of linear uncertain systems with uncertainties which do not matching conditions,the design of satisfactory fault-tolerant control for linear uncertain systems with circle pole and H∞ index constraints was studied.Under a continuous fault model of the actuator,the consistency conditions of two indices fault-tolerant performance are set up by linear matrix inequality approach,and the ranges of constraint indices are analyzed.Furthermore,the effective controller design method for systems with constrains of consistent indices is presented.The simulations for longitude control of aircraft indicate the validity of the proposed methods.更多还原
