Constrained Control Design for Dynamic Positioning of Marine Vehicles with Control Allocation [PDF]
Modeling, Identification and Control, 2009 In this paper, we address the control design problem of positioning of over-actuated marine vehicles with control allocation. The proposed design is based on a combined position and velocity loops in a multi-variable anti-windup implementation together ...

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

Optimizing nonlinear adaptive control allocation [PDF]
Modeling, Identification and Control: A Norwegian Research Bulletin, 2005 A control-Lyapunov approach is used to develop an adaptive optimizing control allocation algorithm for over-actuated mechanical systems where the actuator model is affine in the uncertain parameters. Uniform global (asymptotic) stability is guaranteed by the control allocation defined by the dynamic update laws in combination with an exponentially ...
