This paper focused on for the stability of SPWM inverter affected by digital control. The stability of analog control inverter system, discrete system with no-step-delay control and discrete system with one-step-delay control are analyzed respectively so as to determine the relation of the inverter's sampling period vs. controller parameters with critical stability. Then the essential reason was analyzed...
This note deals with impulsive control of discrete systems with time delay. It's the first time that an impulsive controller was introduced for discrete systems with time delay. Firstly, some stability criteria for delay discrete systems with impulse effects are obtained by using Lyapunov functionals and Razumikhin technique. These stability criteria show that if the impulses satisfy some conditions,...
