Design and Assessment of a Multiple Sensor Fault Tolerant Robust Control System

Abstract EN

This paper presents an enhanced robust control design structure to realise fault tolerance towards sensor faults suitable for multi-input-multi-output (MIMO) systems implementation.

The proposed design permits fault detection and controller elements to be designed with considerations to stability and robustness towards uncertainties besides multiple faults environment on a common mathematical platform.

This framework can also cater to systems requiring fast responses.

A design example is illustrated with a fast, multivariable and unstable system, that is, the double inverted pendulum system.

Results indicate the potential of this design framework to handle fast systems with multiple sensor faults.
