Abstract :
Two different nonlinear observers are employed in the fault diagnosis problem of nonlinear systems. A system with two types of faults (multiplicatives and additives) is analyzed and both faults are estimated with each observer. Some numerical results are shown to illustrate this methodology and finally, some concluding remarks are given
