Fault detection for dissipative nonlinear systems: An energy balance method

This paper addresses the problem of fault detection for dissipative nonlinear systems. A new method based on energy balance is proposed for dissipative nonlinear systems. The nonlinear system is described by the T-S fuzzy model. Based on the dissipation of the T-S fuzzy model, the energy balance is constructed. Then faults can be detected by judging whether the energy balance of system construction is established. The effectiveness of the proposed scheme is illustrated by a numerical example.
