A reconfigurable Direct Control Allocation method
2013 European Control Conference (ECC), 2013In the event of failure of actuators in an overactuated system a reconfigurable law is required to redistribute and coordinate the control effort among the remaining healthy actuators. In this paper, a modified lookup table based Direct Control Allocation method is proposed for reconfiguration of actuator command, for a single actuator fault, without ...

Guidance, Navigation, and Control Conference and Exhibit, 1998
The control allocation problem is defined in terms of solving or approximately solving a system of linear equations subject to constraints for redundant actuator control variable commands. There is one equation for each controlled axis. The constraints arise from actuation rate and position limits.

Disagreement and the Allocation of Control
SSRN Electronic Journal, 2006I study how to allocate control (over one or multiple projects) when people may openly disagree on the optimal course of action. I first show that, in the efficient allocation, complementary decisions should be decided by the same person, while substitute decisions should be decided by different people.

Constrained control allocation
Astrodynamics Conference, 1992This paper addresses the problem of the allocation of several airplane flight controls to the generation of specified body-axis moments. The number of controls is greater than the number of moments being controlled, and the ranges of the controls are constrained to certain limits.

Observer-based nonlinear control allocation
Proceedings of the 2010 American Control Conference, 2010In this paper, a Lyapunov-based approach is proposed for control allocation problem based on output feedback and model reference control. A nonlinear observer design approach for a general class of nonlinear systems is used to estimate the unmeasurable system states.

A hierarchical control architecture for resource allocation
2012 12th International Conference on Control Automation Robotics & Vision (ICARCV), 2012Complex systems consist of a large number of entities with their independent local rules and goals, along with their interactions. In the operations of complex system, such as naval ship, proper decisions and controls are required to keep the system working functionally and effectively.

A nonlinear programming approach for control allocation
Proceedings of the 2004 American Control Conference, 2004A novel nonlinear programming based control allocation scheme is developed. The performance of this nonlinear control allocation algorithm is compared with that of other control allocation approaches, including a mixed optimization scheme, a redistributed pseudo-inverse approach, and a direct allocation (geometric) method.

Adaptive allocation in randomized controlled trials
Controlled Clinical Trials, 1985Adaptive allocation has been proposed as a procedure to reduce the risk of chance imbalance of important prognostic factors in randomized controlled trials when the number of prognostic factors is large. In this article, minimization, a type of adaptive allocation, is compared to simple randomization and stratified allocation in a series of Monte Carlo

Evaluation of Optimization Methods for Control Allocation
Journal of Guidance, Control, and Dynamics, 2001The performanceand computational requirements ofoptimization methodsfor control allocation areevaluated. Two control allocation problems are formulated: a direct allocation method that preserves the directionality of the moment and a mixed optimization method that minimizes the error between the desired and the achieved momentsaswellasthecontroleffort ...
