| 摘 要： | 现有的多发飞机发动机不对称推力自动补偿方法存在着补偿响应速率慢、补偿效果差的弊端,为此提出多发飞机发动机不对称推力自动补偿方法。根据多发飞机发动机失效的实际情况对发动机不对称推力数学模型进行构建,以此为基础,对不对称推力自动补偿控制律进行构造,依据建立的发动机不对称推力数学模型采用不对称推力自动补偿控制律对副翼与方向舵自动补偿增益参数进行计算,实现了多发飞机发动机不对称推力的自动补偿。通过仿真对比实验得到,与现有的多发飞机发动机不对称推力自动补偿方法相比较,提出的多发飞机发动机不对称推力自动补偿方法提升了补偿的响应速率与效果,充分说明提出的多发飞机发动机不对称推力自动补偿方法具备更好的性能。

| Abstract: | The existing automatic compensation methods for asymmetric thrust of multiple-engine have the disadvantages of slow response speed and poor compensation effect.Therefore,an automatic compensation method for asymmetric thrust of multiple-engine is proposed.According to the actual situation of engine failure of multiple aircraft,the mathematical model of engine asymmetric thrust is constructed.On this basis,the control law of asymmetric thrust automatic compensation is constructed.Based on the established mathematical model of engine asymmetric thrust,the parameters of aileron and rudder automatic compensation gain are calculated by using asymmetric thrust automatic compensation control law,and automatic compensation of engine asymmetric thrust.The of multiple aircraft is realized.Compared with the existing automatic compensation methods for asymmetric thrust of multiple-engine,the proposed automatic compensation method for asymmetric thrust of multiple-engine enhances the response rate and effect of compensation,fully demonstrating that the proposed automatic compensation method for asymmetric thrust of multiple-engine has better performance. |
