Fuzzy fault detection of conic-type nonlinear systems within the finite frequency domain

作者：

Highlights：

• Fault detection scheme for conic nonlinear systems in finite frequency domain is designed.

• Sufficient conditions to realize H_ fault sensitivity and H_ disturbance attenuation.

• The fuzzy fault detection problem is transformed into an optimization algorithm.

• A tunnel diode-circuit is given to confirm the validity of the designed scheme.
