Abstract :
An alternative implementation of an algorithm for the computation of the multivariable stability margin to check the robust stability of feedback systems with real parametric uncertainty is proposed. This method eliminates the need for the frequency search by reducing it to the testing of a finite number of conditions. These conditions have a special structure that allows a significant improvement in the speed of computation
