In flight control, control allocation is used to distribute the total control command to each actuator when the number of actuators exceeds the number of controlled variables. A new optimal control allocation method based on nonlinear compensation was proposed in this paper. The quadratic term and mutual-interference effects were introduced into control effectiveness matrix. The linear combination...
In order to improve the reliability, maneuverability and survivability, modern advanced aircrafts generally configure with redundant actuators. To use the potential of redundant configuration and distribute the control power into proper control surfaces, constrained control allocation is introduced to satisfy the desired objectives while avoiding saturation. This paper considers the problem of redesigning...
A hybrid strategy for control allocation of aircraft with multiple effectors is described in this paper. Pseudo inverse method for solution of the control allocation problem is able to find a feasible solution only on a subset of the feasible region. Some other methods, like direct control allocation is able to find the feasible solution on the entire feasible region but have heavy computation burden...
The task of control allocation is to distribute the total control command to each actuator when the number of actuators exceeds the number of controlled variables. In this paper, the effects of uncertainty of flight control system on control allocation algorithms are examined. The uncertainties of control allocation algorithm result from model uncertainties are analyzed firstly. Then three control...
