Abstract: The object of this paper is the oscillatory stable regime of a particular nonlinear system. This particular nonlinear system includes a relay, and its linear part is characterized by a transfer function with two time constants. In the beginning, the paper shows a method that can be used in the calculus of the parameters for the limit stable cycle, which is appropriated for these nonlinear systems. After that, the method is particularized for two different commutation lows of the relay nonlinearity: relay with hysteresis and relay with delay time. The different commutation laws induced, for the same linear parts, different shapes and parameters for the oscillatory stable regimes proper to assembly nonlinear system. These differences are presented in a case study.
