This paper presents an analysis of a class of two-relay feedback systems, motivated by the idea of estimating a relay-type nonlinearity on the feedback path of a plant by adding another relay. The time response of the resulting system is analyzed and stability conditions are obtained using Poincaré's method. A simple procedure for estimating the unknown value (Coulomb friction) of the relay on a plant feedback is presented and illustrated on both simulated and real time examples.
