摘要: 基于近似模型和遗传算法,针对多操纵面布局飞机提出一种对全包线飞行控制律和操纵效率器几何形状与位置进行多学科优化的设计方法.该方法采用力矩控制方式进行控制,应用鲁棒增益调参方法设计全包线飞行控制系统,利用试验设计方法和径向基神经网络响应面获取近似的气动学科模型和控制学科模型,在近似模型基础上由遗传算法获得优化的设计参数并最终获得优化的控制律和操纵效率器.以某多操纵面布局无尾飞机为例进行计算机飞行仿真验证,结果表明该方法具有可行性.

Abstract: Based on approximate models and genetic arithmetic, a scheme for the plane with multi-flaps was proposed to implement the multidisciplinary design optimization (MDO) of full-envelope flight control law and control effectors- geometry & their placement. The robust gain-schedule control method was applied to develop the full-envelope flight control system with the form of moment control in this scheme, and design of experiment (DOE) method as well as radial basis function nerve-network (RBF NN) response surface method was used to obtain approximate models for aerodynamics discipline and control discipline. Then the optimized design parameters were achieved with the genetic arithmetic based on approximate models, and the optimized flight control low & control effectors were finally obtained. On the computer the scheme was validated for a tailless plane with multi-flaps. The simulation result shows the feasibility of the scheme.
