Abstract
The describing function method is used to predict the existence of limit cycles in a system with a separable nonlinearity. The results are obtained graphically or analytically by determining the intersection of the frequency for the linear subsystem and the describing function. Here, the authors combine well known Kharitonov theorems with the describing function to test the stability of uncertain systems. An example is provided to illustrate the new method
