基于非线性逆变换的控制选择器设计

提出一种非线性逆变换控制选择器的设计方法，并成功地应用于先进短距起飞／垂直着陆（ＡＳ－ＴＯＶＬ）技术的战斗机控制系统。该方法基于非线性逆变换原理，对飞机进行多气幼舵面和多推力矢量舵面的融合控制，合理地分配飞机上的力和力矩，克服了传统设计方法的不足，使设计简单化。最后通过ＡＳＴＯＶＬ飞机减速过渡的仿真计算与分析，证明了所设计的控制选择器，能够使飞机在低速飞行包线内具有良好的飞行品质。

Design of control selector based on nonlinear inversion transformation

A designing method of controlled selector with nonlinear inversion transformation is proposed, which is successfully applied to control system for advanced short takeoff and vertical landing(ASTOVL). The main idea of the method is, based on the theory of nonlinear inversion transformation, that syncretizing control of multi aerodynamic rudder and multi thrust vector rudder is implemented to distribute the force and moment on the fighter with reason. This method overcomes the deficiency of traditional ways and makes design methods simply to be implemented in practice. At last the simulation analysis of decelerating transition for ASTOVL shows that controlled selector designed possess the favorable flying qualities in the low speed performance envelope.
