| 摘要: |
| 提出发动机推力档位缺失下自动推力计算方法，该方法利用配平线性化方法求取发动机推力2个档位之间的等效油门开度，以等效油门开度为权值给出了自动推力计算方法；设计了引入等效油门开度的速度控制系统，将该系统与垂直速度控制系统联合，实现了飞行仿真中的爬升、下滑、给定偏航角、给定滚转角4种基本模态，以及特殊速度控制模态的速度控制。以空客A320为例，从JSBSim获取气动参数以及发动机的慢车推力和最大推力系数，通过Simulink搭建飞行仿真模型，对上述模态进行了飞行控制仿真，结果表明提出的方法能够实现多飞行模态速度的精确控制。 |

| Abstract: |
| The paper proposes an automatic thrust calculation method in the case of engine gear missing. The trimmed linearization method is used to calculate the equivalent throttle opening between the two gears. An automatic thrust calculation method is presented which uses the equivalent throttle opening as weight coefficient. The speed control system which has introduced the equivalent throttle opening is designed, and the speed is controlled through the combination of the speed control system and the vertical speed control system. In this way, four basic modes are realized in flight simulation——climb, glide, given the yaw angle, given the roll angle, and the special speed control mode. It takes A320 aircraft for an example, the aerodynamic parameters and the Idletrust and Miltrust coefficients are obtained from JSBSim. Carry out flight control simulation on the above modes by building aircraft flight simulation model through Simulink. The results of the flight speed control show that the proposed method can achieve precise control of the speed in multi-flight modes. |
