摘　　要：单发螺旋桨飞机平飞角度控制是提高单发螺旋桨飞行效率,保证飞行安全的关键。单发螺旋桨结构的飞机飞行中,动力控制不像双桨飞机容易控制平衡,飞行过程不可避免的发生侧滑。运用传统的方法进行平飞角度控制的过程中,在侧滑的情况下,螺旋桨上的受力符合会发生不均匀分布,导致控制精度下降。为提高控制精度,提出采用控制反馈补偿算法的单发螺旋桨飞机平飞角度控制方法。采用伪攻角和姿态角相结合的反馈形式进行平飞角度速率反馈,建立平飞角度控制模型。在模型的参数选取过程中,充分考虑到主观因素造成的偏差,对偏差进行补偿,获取满足单发螺旋桨飞机平飞角度控制稳定性需求的参数,从而实现了平飞角度的精确控制。实验结果表明,利用改进算法进行单发螺旋桨飞机平飞角度控制,能够有效提高控制的精确度。The angle control of single propeller-driven aircraft in level flight is to improve the flight efficiency of single propeller-driven aircraft, and the key to ensure flight safety. In order to improve the control precision, an an- gle control method for single propelled-driven aircraft in level flight was proposed based on control feedback compen- sation algorithm. The feedback form with the combination of pseudo attack angle and attitude angle was used to make rate feedback of the angle in level flight and establish the control model of angle control in level flight. In the parame- ters selection process of the model, the deviation caused by subjective factors was fully considered, the deviation was compensated, and the parameters to meet the stability demand of the angle control of single propelled-driven aircraft in level flight can be obtained, so as to realize the precise control of the angle in level flight. Experimental results show that using the improved algorithm for angle control of single propeller-driven aircraft in level flight, can effec- tively improve the accuracy of the control.
