摘要：为实现飞机行进轨迹多波段同时调节，使其飞行姿态能够受到软件程序的有效控制，设计基于PWPF调制技术的飞机飞行姿态控制系统软件程序。根据时钟配置情况，设置CAN通信接口，并以此为基础，完成对导航仪与舵机状态的检测，再联合偏航距离校正结果，规范核心控制程序的编写形式，实现系统各软件模块功能的设计。建立自抗扰闭环，按照PWPF调制技术的静态作用需求，求解二次规划函数，完成基于PWPF调制技术的控制机制定义。在反步控制器运行过程中，推导非线性建模表达式，实现对飞机飞行姿态控制行为的建模，完成基于PWPF调制技术的飞机飞行姿态控制系统软件设计。实验结果表明，基于PWPF调制技术所设计的软件程序，在X波、C波、S波、L波的波频范围内，均能有效控制飞机的飞行姿态，与多波段调节飞机行进轨迹的实际应用诉求相符合。

Software Design of Aircraft Flight Attitude Control System Based on Pwpf Modulation Technology
Abstract：In order to realize multi-band simultaneous adjustment of aircraft flight path and make its flight attitude be effectively controlled by software program, the software program of aircraft flight attitude control system based on PWPF modulation technology is designed. According to the clock configuration, set the CAN communication interface, and on this basis, complete the detection of the status of the navigator and the steering gear, and then combine the yaw distance correction results to standardize the writing form of the core control program, and realize the design of the functions of each software module of the system. Establish the auto-disturbance rejection closed-loop, solve the quadratic programming function according to the static function requirements of PWPF modulation technology, and complete the definition of control mechanism based on PWPF modulation technology. During the operation of the backstepping controller, the nonlinear modeling expression is derived to realize the modeling of aircraft flight attitude control behavior, and the software design of aircraft flight attitude control system based on PWPF modulation technology is completed. The experimental results show that the software program designed based on the PWPF modulation technology can effectively control the flight attitude of the aircraft within the wave frequency range of X wave, C wave, S wave and L wave, which is consistent with the practical application requirements of multi-band adjustment of the aircraft travel path.
