Abstract

Dealing with the complexity of modern technological non-linear systems and their disturbances is a very challenging issue. Sliding Mode Control (SMC) can deal perfectly with the non-linear systems and their disturbances because its accuracy and stability are very high. In this paper, a brief review of SMC types, SMC methods, and SMC in the field of Fault Tolerant Control (FTC), are provided. It also gives brief details about the reaching phase, sliding phase, and sliding surface, with their advantages and disadvantages. Further, chattering, which is the main drawback of SMC, is discussed and methods to resolve the chattering are also provided. In the end, various types of FTC are discussed and potential use of SMC in the design of FTC has been described. This paper will give comprehensive state-of-the-art to new researchers about the implementation of SMC in the FTC domain for further research.

Keywords: Sliding mode control, fault tolerant control, sliding surface, reaching surface, chattering, SMC algorithms, control allocation.
