✦ Synopsis

In this paper suboptimality bounds and stability of nonlinear discrete-time in"nite-horizon controllers are investigated. The nominal plant is supposed to be controlled by means of a feedback control law which is optimal with respect to some given criterion. The use of the Taylor}Maclaurin formula appears to be the key to establish the suboptimality properties of the decentralized control and at the same time to derive upper and lower bounds on the suboptimality.
