In case of the sustained oscillations caused by the non-linear characteristics, we can not discuss on the utility of controllers, without the calculations of their amplitude and frequency. From this standpoint, an example of the non-linear characteristics in the relay is treated in this paper. First, we devided the non-linear characteristics into three linear sections and treated this each section by linear vibration theory, then we obtained the sustained oscillations by numerical calculations. Secondly, we approximately represented the characteristics by cubic curve and analytically treated it on the assumption that the sustained oscillations are represented as simple harmonic motions. As the results, we confirmed analytically that the amplitude and frequency of the sustained oscillations caused by the non-linearity are independent of the initial disturbances, and that the frequency is independent of the shape of the characteristics in the relay.
