“…The control strategies which can control a system during both healthy and failure conditions are known as fault-tolerant control (FTC) systems. [3][4][5] These systems are generally divided into passive and active systems. In passive systems, a robust controller (eg, H ∞ ) is used during prefault and postfault conditions.…”

Background: 3ϕ Induction Machine (IM) drives are broadly used in different industrial applications. During failure conditions, 3ϕ IM drive systems cannot continue its optimal performance. Aims: The present study presents a method for indirect rotor field-orientated control (IRFOC) of star-connected 3ϕ IM drives during open-phase failure (OPF) condition. In addition, in this study the particle swarm optimization algorithm was used to determine the coefficients of proportional-integral (PI) controllers in the OPF mode. Materials & Methods: In the proposed method, two unbalanced currents and voltage rotational matrices are utilized to change the asymmetrical structure of the faulty 3ϕ IM equations to the equations with a symmetrical structure. Using these matrices, the speed control of the faulty 3ϕ IM can be realized with minor changes in the conventional IRFOC structure including control parameters, transformation matrices, and coefficients of PI controllers. Results: Experimental results were presented during various operating conditions on a 1 HP star-connected 3ϕ IM drive system. Discussion: The experimental tests in different operating conditions showed good performances of the proposed control system during both the steady-state and the transient periods. Conclusion: The proposed control method exhibited a significant improvement in reducing the speed, torque, and flux oscillations, compared to the

“…In addition, the time delay inherent to mechanical systems also affects the performance of FTC. FTC strategies can be divided into two categories: passive FTC (PFTC) [1,2] and active FTC (AFTC) [3,4]. In PFTC, the control performances mainly depend on the robust capability dealing with uncertainties/disturbances of the controller such as sliding mode control [5] or adaptive control [6,7].…”

In this paper, an active fault-tolerant control for a robot manipulator based on synchronous sliding mode is proposed. As the synchronization errors approach zero, the joint errors tend to become equal and also approach zero. Therefore, the synchronization technique is inherently effective for a fault-tolerant controller. To demonstrate such a system, the following implementation is presented. First, an estimator was designed with an extended state observer to estimate uncertainties/disturbances along with faults/failures. The estimator signal was used for an online compensator in the controller. A fault-tolerant controller with a combination of synchronous sliding mode technique and estimator was proposed. The stability of the system was established using Lyapunov theory. Finally, fault tolerant control was implemented in a three degree-of-freedom robot manipulator and compared to the conventional sliding mode control. This comparison shows the effectiveness of the proposed active fault-tolerant control with synchronous sliding mode technique.

“…At present, the control reconfiguration is generally studied from the perspective of fault-tolerant control (FTC), which has been widely applied to some safety-critical systems, especially in the field of aerospace engineering [3], a large number of FTC methods have been proposed. The most popular ones for control reconfiguration can be roughly divided into the categories as: adaptive control [4]- [6], control allocation [7]- [9], sliding mode control [10]- [12], multi-model switching [13]- [15], and other nonlinear control methods [16]. And the fault types considered in most studies mainly fall on sensor fault, actuator fault and the fault of structural damage.…”

The thrust loss fault of the space launch vehicle is quite different from that of ordinary actuator efficiency loss. Focusing on the attitude tracking control problem of the launch vehicle with thrust loss fault, the special impacts of that fault on the control system are explored, and a two-stage control reconfiguration strategy based on the cascaded pseudo-inverse allocation method and the neuron adaptive gain scheduling method is proposed for faults with different severity. Meanwhile, a practical reconfigurability analysis for the faulty system based on the control state reachability is presented for some representative fault scenarios. Based on the nonlinear dynamical model of the faulty system, lots of numerical simulations under various fault scenarios are finally carried out. The results indicate that the designed control reconfiguration strategy not only can effectively deal with the thrust loss fault with high practicability but also is easy to implement. INDEX TERMS Space launch vehicle, thrust loss fault, control reconfiguration strategy, cascaded pseudo-inverse allocation, neuron adaptive gain scheduling, reconfigurability analysis.
