Control System Design and Emulation for Vectored Thrust Aircraft

针对某型推力矢量飞机提出了一套控制方案,较好地将理论与工程实践结合起来,解决了飞机在全包线范围内的飞行控制问题。该控制方案包括常规机动控制器、大迎角超机动控制器、控制分配器及轨迹跟踪控制器等几个主要环节的设计,完成的控制系统满足全包线飞行品质的要求,可实现对大机动轨迹的精确跟踪。最后,对此综合控制系统进行数字仿真并给出部分仿真结果,结果表明所提出的飞行控制系统设计方案是成功的。

For certain of vectored thrust aircraft, this paper introduces a set of control scheme which integrates theoretic with engineering practice well and solves the problems of full-envelope flight control. The scheme included the design of the following main controller： conventional maneuver controller, large angle super maneuver controller, control allocation mixer and trajectory tracking controller. The whole control system can fulfill the requests of full-envelope flying qualities and track the large maneuverable trajectory accurately. Finally, digital simulation for the control system was made and some simulating results were presented. The results show that the scheme of the flight control system is successful.
