Abstract :
This paper gives an extension of the absolute stability analysis of systems whose forward path contains a linear time-invariant subsystem with uncertain coefficients and whose feedback path contains a conic nonlinearity. The results provide a simple frequency domain interpretation of stability that can be of importance in compensator design and robust stability analysis in nonlinear systems
