Abstract :
A grapho-analytical method for the determination of self-sustained oscillations in a nonlinear system having two nonlinear memoryless energyless elements, separated by a linear device is proposed. The method relies on the graphical solution of the system equations, derived by harmonic linearization of the nonlinear functions that describe the two nonlinear elements.
