Actuator and Sensor Fault-tolerant Control Design

Abstract

Many industrial systems are complex and nonlinear. When it is not easy to deal with the nonlinear models, systems are usually described by linear or linearized models around operating points. This notion of operating point is very important when a linearized model is considered, but it is not always easily understood. The objective in this chapter is to highlight the way to seek an operating point and to show a complete procedure which includes the identification step, the design of the control law, the FDI, and the FTC. In addition to the detailed approach dealing with linearized systems around an operation point, a nonlinear approach will be presented.
