    摘要:

    為實(shí)現飛機行進(jìn)軌跡多波段同時(shí)調節,使其飛行姿態(tài)能夠受到軟件程序的有效控制,設計基于PWPF調制技術(shù)的飛機飛行姿態(tài)控制系統軟件程序。根據時(shí)鐘配置情況,設置CAN通信接口,并以此為基礎,完成對導航儀與舵機狀態(tài)的檢測,再聯(lián)合偏航距離校正結果,規范核心控制程序的編寫(xiě)形式,實(shí)現系統各軟件模塊功能的設計。建立自抗擾閉環(huán),按照PWPF調制技術(shù)的靜態(tài)作用需求,求解二次規劃函數,完成基于PWPF調制技術(shù)的控制機制定義。在反步控制器運行過(guò)程中,推導非線(xiàn)性建模表達式,實(shí)現對飛機飛行姿態(tài)控制行為的建模,完成基于PWPF調制技術(shù)的飛機飛行姿態(tài)控制系統軟件設計。實(shí)驗結果表明,基于PWPF調制技術(shù)所設計的軟件程序,在X波、C波、S波、L波的波頻范圍內,均能有效控制飛機的飛行姿態(tài),與多波段調節飛機行進(jìn)軌跡的實(shí)際應用訴求相符合。

    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.
