This paper investigates the problem of optimal fault-tolerant control (FTC) for a class of unknown nonlinear discrete-time systems with actuator fault in the framework of adaptive critic design (ACD).

In this letter, we study the energy-optimal control of nonlinear port-Hamiltonian (pH) systems in discrete time. For continuous-time pH systems, energy-optimal control problems are strictly ...

Specifically, on the optimality issue for fuzzy control systems (Yonmook Park et al., 2004). A good optimal control technique, especially when applied for the first time on a particular process, ...
