Description

The key attribute of a Fault Tolerant Control (FTC) system is its ability to maintain�overall system stability and acceptable performance in the face of faults and�failures within the feedback system. In this book Integral Sliding Mode (ISM) Control�Allocation (CA) schemes for FTC are described, which have the potential to�maintain close to nominal fault-free performance (for the entire system response),�in the face of actuator faults and even complete failures of certain actuators. Broadly�an ISM controller based around a model of the plant with the aim of creating a�nonlinear fault tolerant feedback controller whose closed-loop performance is established�during the design process. The second approach involves retro-fitting an�ISM scheme to an existing feedback controller to introduce fault tolerance. This�may be advantageous from an industrial perspective, because fault tolerance can be�introduced without changing the existing control loops. A high fidelity benchmark�model of a large transport aircraft is used to demonstrate the efficacy of the FTC�schemes. In particular a scheme based on an LPV representation has been implemented�and tested on a motion flight simulator.Typham this is the title: Fault Tolerant Control Schemes Using Integral Sliding Modes
