Adaptive Reliable Control against Sensor Faults

In Chapter 3, a new reliable control approach for linear systems against actuator faults is proposed, based on the combination of adaptive method and linear matrix inequality technique. A control system consists of sensors, compensators and actuators besides a controlled object. In general, sensors are prone to break down more frequently than actuators or compensators. Furthermore, sensor faults are prone to bring about more serious situations than actuator of compensator faults. It is because incorrect information from a failed sensor often makes the total control system in danger. Measures should be fully taken against sensor faults in many control systems [150, 154]. Currently, the research about fault-tolerant control against sensor faults has been paid more attention [83, 87, 88, 150].
