Abstract:

A novel multi-object nonlinear control allocation method is brought forward in this article. The theory, modeling and problem solving of the method are presented in detail. The evaluation indexes and evaluation way of the multi-object nonlinear control allocation solution are described. The multi-object nonlinear control allocation method does not rely on the assumption that the produced pseudocontrol commands, generally pitch, yaw and roll moments are linear relation with the generalized control effector deflections. The method can deal with the nonlinear relation between the produced moments and the control effector deflections directly. It can also make full use of the redundant control effectors to realize the integrated tradeoff multiobject control allocation under varying flight conditions and missions. The simulation results show that the control allocation method is effective and very satisfactory simulation accuracy is obtained. It can handle the control allocation problem under the circumstance of the aircraft effector fault and provide algorithm guarantee for reconfiguration .
