“…In the FTC scheme which will be proposed, the fault information (i.e., the matrix W ) is not required for the control allocation scheme and hence the scheme can be regarded as "passive" (Verhaegen et al, 2010). The proposed strategy "distributes" the control effort among all the actuators and constitutes a passive fault tolerant control scheme.…”

In this paper, integral sliding mode control ideas are combined with direct control allocation in order to create a fault tolerant control scheme. Traditional integral sliding mode control can directly handle actuator faults; however, it cannot do so with actuator failures. Therefore, a mechanism needs to be adopted to distribute the control effort amongst the remaining functioning actuators in cases of faults or failures, so that an acceptable level of closed-loop performance can be retained. This paper considers the possibility of introducing fault tolerance even if fault or failure information is not provided to the control strategy. To demonstrate the efficacy of the proposed scheme, a high fidelity nonlinear model of a large civil aircraft is considered in the simulations in the presence of wind, gusts and sensor noise.

“…To represent the actuator faults in a more general formulation, the following mathematical model can be used [26]: (1) where () a ut is faulty actuator output, () a ftcontains the values at which the actuators are stuck or floating or hard-over. I is the identity matrix and 0 a i   represents a total fault (i.e.…”

Level control of liquids in coupled tanks is a basic requirement in many industrial processes. Liquid levels in tanks must be controlled accurately regardless of environmental circumstances. Minor faults in sensors, actuators or other system components that take place in processes where liquid level control is required can result in catastrophic consequences. In this case, a fault tolerant control system is needed. The controller must be either robust (passive) or in reconfigurable (active) type in order to compensate for the effect of actuator faults and maintain system reliability and performance. In this study, a water tank level control system and possible valve actuator faults are modelled. By designing different controllers and using modelled failures a simulation is constructed. To test the reconfigurable type controller performance against faults/failures, a model reference adaptive control system is implemented and compared with PI-controlled system.

“…This is in fact an aggressive choice for ϱ(x) because the nonlinear term in (44) can contribute a signal in the range [−0.65, 0.65] rad to the value of the overall virtual control signal because of the signum term. The units of the control signal are radians 4 and so this range represents a significant portion of the available/allowable control signal variation. It does however mean that significant errors in the estimation of w i (t) can be tolerated.…”

“…Many different schemes have been proposed, ranging from active to passive control methods [1], with applications running the gamut from large scale petrochemical plants to automotive and aerospace systems [2]. The work in [1], [2], [3], [4] provides an excellent literature review on the different schemes used for FTC including different applications; however, research into FTC has been significantly driven by problems encountered in the safety critical aerospace industry. This is due to the practical requirement for increasing safety as well as lowering operational costs.…”

This paper proposes a novel nonlinear fault tolerant scheme for longitudinal control of an aircraft system, comprising an integral sliding mode control allocation scheme and a backstepping structure. In fault free conditions, the closed loop system is governed by the backstepping controller and the integral sliding mode control allocation scheme only influences the performance if faults/failures occur in the primary control surfaces. In this situation the allocation scheme redistributes the control signals to the secondary control surfaces and the scheme is able to tolerate total failures in the primary actuator. A backstepping scheme taken from the existing literature is designed for flight path angle tracking (based on the nonlinear equations of motion) and this is used as the underlying baseline controller in nominal conditions. The efficacy of the scheme is demonstrated using a high fidelity aircraft benchmark model. Excellent results are obtained in the presence of plant/model uncertainty in both fault-free and faulty conditions.
