It is demonstrated that the stable SDD impulsive system suffers from unstable impulse interference, the system is still able to maintain the ISS property. Conversely, we have developed a set of sufficient conditions, founded on Lyapunov theory, to evaluate the ISS state of the system based on the impulse control strategy. It has been demonstrated that the intrinsically unstable SDD impulsive system can also maintain the ISS state and attain the anticipated performance. To conclude, we have presented two numerical cases to substantiate the precision and practicality of the theoretical outcomes.展开更多
