Fault-tolerant Control Design for Linear Systems with Input Constraints and Actuator Failures
This paper presents an active fault-tolerant control (FTC) scheme for linear systems subject to input constraints and actuator failures. The proposed scheme is based on integrating model predictive control (MPC), faultdetection filter and soft switching approach. Multiple MPC controllers are designed beforehand; one is used as primary control configuration, and the others are used as backup control configurations. A fault-detection filter is designed to detect actuator faults. Once a fault is detected and the fault information is submitted to the supervisor, one of the backup control configurations is switched to using soft switching approach. This FTC scheme provides a new framework to deal with input constraints and actuator failures simultaneously. An example is given to illustrate the effectiveness of the proposed method.
