A SIMULATION STUDY OF UNSTABLE LIMIT CYCLES

Abstract The paper describes investigations of unstable limit cycles in nonlinear feedback systems. The question of interest was the ability of a digital simulation language to find and to continue to track unstable limit cycles. The existence of any unstable limit cycles and then stability was found using extensions of Tsypkin’s method for relay systems. The simulations confirmed the relative stability of the limit cycles predicted by this method.
