【Abstract】 The robust fault-tolerant control problem is studied for uncertain linear discrete systems. A sufficient condition of robust stability for uncertain linear discrete systems with sensor failures based on a reduced order state observer is proposed. Also the design method of robust fault-tolerant controller is discussed. A numerical example is given to illustrate the design procedure and its effectiveness.更多还原
