Actuator Fault Tolerant Control of Variable Cycle Engine Using Sliding Mode Control Scheme
Actuators, 2021 This paper presents a fault tolerant control (FTC) design for the actuator faults in a variable cycle engine (VCE). Ensured by the multiple variable geometries structure of VCE, the design is realized by distributing the control effort among the unfaulty

Resource balancing control allocation [PDF]
Proceedings of the 2010 American Control Conference, 2010 Next generation aircraft with a large number of actuators will require advanced control allocation methods to compute the actuator commands needed to follow desired trajectories while respecting system constraints. Previously, algorithms were proposed to minimize the l 1 or l 2 norms of the tracking error and of the control effort.

A Fault-Tolerant Steering Prototype for X-Rudder Underwater Vehicles
Sensors, 2020 The X-rudder concept has been applied to more and more autonomous underwater vehicles (AUVs) in recent years, since it shows better maneuverability and robustness against rudder failure compared to the traditional cruciform rudder.

Computationally efficient control allocation [PDF]
Guidance, Navigation, and Control Conference and Exhibit, 1999 A computationally efficient method for calculating near-optimal solutions to the three-objective, linear control allocation problem is disclosed. The control allocation problem is that of distributing the effort of redundant control effectors to achieve some desired set of objectives. The problem is deemed linear if control effectiveness is affine with
