Abstract

This note derives persistence of excitation conditions on the input for systems with partially known transfer functions. The assumed transfer function model is [p0(s) + KTP(s)][q0(s) + KTQ(s)], where K is the unknown parameter vector p0(s), q0(s) are known scalar polynomials and P(s) and Q(s) are known vector polynomials.
