Abstract :
A simple inequality giving both upper and lower bounds on suboptimality is developed and shown to be applicable in estimating 1) the cost of uncertainty in plant parameters, and 2) the cost of decentralized control in interconnected systems. In this second problem the results yield a "weak coupling" condition guaranteeing the stability of a simple decentralized control scheme.
