Signal stabilization of hysteresis type relay systems

The use of signal stabilization as a means of stabilizing non-linear systems has been known for a long time. Very recently, the method of obtaining the minimum amplitude of dither signal for a relay type nonlinear system was also established. An empirical relationship for the minimum amplitude of dither required for quenching the limit cycles in a nonlinear system with a relay with hysteresis type nonlinearity is obtained.
