Abstract :
H∞ control problems for digital control systems are investigated in both finite and infinite horizon cases. Necessary and sufficient conditions are obtained for the existence of controllers that satisfy a specified H∞ performance bound. These conditions are stated in terms of Riccati differential equations with jumps. When these conditions hold, explicit formulas for a controller satisfying the H∞ performance bound are given
