In this paper, the absolute stability of general Lurie type robust control system has been discussed by using the method of Lyapunov function. Some more practical sufficient conditions of absolute stability for the above system are obtained by adjusting the coefficients of Lyapunov functions and parameters of S-procedure. Examples are given to illustrate the method of this paper and the application of new algebraic criteria for absolute stability.
