Abstract

ABSTRACT An adaptive dynamic programming (ADP)‐based fault‐tolerant control (FTC) scheme integrating a sliding mode surface (SMS) and an event‐triggered mechanism is developed for a class of nonlinear systems with unknown actuator faults. A fault estimation observer is constructed, and its outputs are embedded into a formulated performance index, thereby recasting the FTC problem as a tractable optimal control problem. Within the resulting ADP framework, a controller is synthesized that automatically delivers active and optimal fault compensation. In place of conventional actor‐critic neural network (ACNN) architectures, a simplified critic‐only neural network (NN) is adopted, together with policy iteration,…
