Abstract

A reliable control system design scheme against sensor failure is proposed. In addition to the primary output sensor, redundant dissimilar sensors are used to measure different system variables which are more easily accessible and dynamically related to the desired system output. In the event of output sensor failure, the measured signal from the redundant sensor can still maintain the system feedback, the system stability and certain performance, such as, tracking ability. An illustrative example is presented to demonstrate the effectiveness of the proposed design strategy
