The purpose of this paper is to investigate the impulsive exponential stabilization for the positive equilibrium points of a class of discrete population growth models with time delays. By using Lyapunov functionals, some new exponential stability criteria are given. It is shown that impulses can indeed make unstable equilibrium points exponentially stable, and when the impulses are employed to stabilize...
The optimal tracking controller for discrete-time systems with time-delayed in state and input under disturbance is considered. By introducing a variable transformation, the system with disturbance and time-delayed in state and input is transformed into a non-delayed system with disturbance, and the quadratic performance index of the optimal tracking control is transformed into a relevant format....
