TL;DR: This paper addresses the problem of fault-tolerant control for Takagi-Sugeno (T-S) fuzzy systems with actuator faults with a general actuator fault model, and sliding-mode observers (SMOs) are designed to provide a bank of residuals for fault detection and isolation.
Abstract: This paper addresses the problem of fault-tolerant control for Takagi-Sugeno (T-S) fuzzy systems with actuator faults First, a general actuator fault model is proposed, which integrates time-varying bias faults and time-varying gain faults Then, sliding-mode observers (SMOs) are designed to provide a bank of residuals for fault detection and isolation Based on Lyapunov stability theory, a novel fault-diagnostic algorithm is proposed to estimate the actuator fault, which removes the classical assumption that the time derivative of the output errors should be known as in some existing work Further, a novel fault-estimation observer is designed Utilizing the estimated actuator fault, an accommodation scheme is proposed to compensate for the effect of the fault In addition, a sufficient condition for the existence of SMOs is derived according to Lyapunov stability theory Finally, simulation results of a near-space hypersonic vehicle are presented to demonstrate the efficiency of the proposed approach

TL;DR: The proposed integrated design approach using FE and fault compensation within the control system in which the design is achieved by integrating together the FE and FTC controller modules is illustrated through studying the control of an uncertain model of a DC motor.

TL;DR: In this paper, controllability tests and motion control algorithms for underactuated mechanical control systems on Lie groups with Lagrangian equal to kinetic energy were provided, and two algebraic tests were derived in terms of the symmetric product and the Lie bracket of the input vector fields.
Abstract: We provide controllability tests and motion control algorithms for underactuated mechanical control systems on Lie groups with Lagrangian equal to kinetic energy. Examples include satellite and underwater vehicle control systems with the number of control inputs less than the dimension of the configuration space. Local controllability properties of these systems are characterized, and two algebraic tests are derived in terms of the symmetric product and the Lie bracket of the input vector fields. Perturbation theory is applied to compute approximate solutions for the system under small-amplitude forcing; in-phase signals play a crucial role in achieving motion along symmetric product directions. Motion control algorithms are then designed to solve problems of point-to-point reconfiguration, static interpolation and exponential stabilization. We illustrate the theoretical results and the algorithms with applications to models of planar rigid bodies, satellites and underwater vehicles.
