A Comparison of Control Allocation Methods for the F-15 ACTIVE Research Aircraft Utilizing Real-Time Piloted Simulations
A comparison of two control allocation methods is performed utilizing the F-15 ACTIVE research vehicle. The control allocator currently implemented on the aircraft is replaced in the simulation with a control allocator that accounts for both control effector positions and rates. Validation of the …

Fair resource allocation in multiple access channels
We consider the problem of resource allocation in a multiple access channel. Our objective is to obtain rate and power allocation policies that maximize a general concave utility function of average transmission rates over the information theoretic capacity region of the multiple-access channel. We …
