摘要
In this paper we derive guaranteed gain, sector, and disk margins for discrete-time nonlinear optimal and inverse optimal regulators that minimize a nonlinear-nonquadratic performance criterion. The proposed results provide a transparent generalization of the classical discrete-time, linear-quadratic optimal regulator gain and phase margins. Finally, connections are also made between discrete-time control Lyapunov functions and inverse optimality.
