Abstract :
In this paper, two methods based on optimal control theory and Lyapunov stability theory are used to construct aggrandized disturbances. According to the concepts of isochrones and switch-curves, some results are given in detail for second order and third order stable control systems. With the help of these isochrones and switch-curves, it is easy to assess the vulnerability to dynamic stress of a closed loop stabilized system
