【Abstract】 The stability of discrete descriptor system is considered, and it is equivalent to Lyapunov equation with positive definite solution for discrete descriptor systems. The relationship among R- observable, stability and Lyapunov equation with positive definite solution is investigated. The condition on which discrete descriptor system is regular, stable and causal is studied based on the established Lyapunov equation.更多还原
