Abstract :
We investigate the stability and robustness of nonlinear, adaptive feedback systems of the form: z(t) = - LN z (t) + r(t). Here z(t) is an input signal, r(t) is a bounded input, L is a linear, casual operator and N is a sector bonded nonlinearity representing model uncertainties due to nonlinearities and low order modeling. The above feedback system arises where we use nonlinear model feeback control with sodel mismatch.
