Abstract

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 allocation methods including direct allocation method, cascaded generalized inverse method and fixed-point method are compared using aircraft model with control effectiveness uncertainties. The simulation results demonstrate the influences of uncertainties to the control allocation results.
