Abstract :
A sufficient condition is derived for the existence of a stable suboptimal ℋ∞ controller. It is shown that if a certain algebraic Riccati equation, determined from a parameterization of all suboptimal ℋ∞ controllers, has a positive definite stabilizing solution, then a stable ℋ∞ controller of order 2n can be constructed, where n is the order of the generalized plant
