In this paper, we study the control problem of auto-berthing marine surface vessels (MSVs) within a predefined, finite time in the restricted waters of a port, in the face of internal and external uncertain dynamics and actuator faults. We first use

In this article, a new intelligent fault-tolerant control (FTC) is designed to control a flexible-link manipulator with uncertain dead-zone and intermittent actuator faults. Initially, a smooth dead-zone inverse model using a hyperbolic tangent funct

This paper focuses on an iterative learning fault-tolerant control strategy for discrete-time affine nonlinear systems where actuator faults arbitrarily occur. First of all, the actuator fault is decomposed into multiplicative model and additive one.
