无人机飞行控制系统优化设计

An Optimization Design of Flight Control System of RPV

在小型无人机飞行控制系统经典设计的基础上，结合实际工程需要，应用多目标参数最优化方法对飞行控制系统进行优化设计。实际工程应用表明，优化设计明显改善了小型无人机飞行品质，保证了系统任务的可靠执行。

To satisfy stringent requirements of night performance of remotely piloted vehicle (RPV ), conventional methods for designing its flight control system (FCS) need to be improved through optimization. Our method of multi -objective optimhation is simple so that it can be easily implemented. We do not alter the mathematical model of the originai optimization problem but replace all parameters-static or dynamic, concentrated or distributed with static ones. We discuss in detail six aspects of our optimization design: (1) mathematical model, (2) control architecture, (3) performance criteria, (4) constraint conditions, (5) optimisation algorithm, (6) system software.Figs. 4 and 5 show that actual RPV flight performance is improved. Fig. 4 shows the RPV flight performance obtained with control system based on conventional method of design. Fig. 5 shows the much better RPV flight performance obtained with the control system based on our simple optimization method of design.
