This paper presents an enhanced robust control design structure to realise fault tolerance towards sensor faults suitable for multi-input-multioutput (MIMO) systems implementation. The proposed design permits fault detection and controller elements to be designed with considerations of 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.
