摘要
人感系统为飞行员操纵飞机提供必须的操纵感觉,是影响飞机操纵品质及性能的主要因素。随着对飞机操纵品质的要求越来越高,优化人感系统的性能显得尤为迫切和重要。由于主动驾驶杆可以根据飞机飞行状态实时调参,因此,能够有效提高飞机的操纵品质,成为人感系统研究的热点之一。主动驾驶杆是指力、位移、阻尼等人感特性可以随飞机状态进行实时调节的操纵装置。相对于被动杆,主动杆最大的特点是杆力特性中引入飞行参数,将飞行员感受到的力与飞机的飞行状态联系起来。文中系统介绍了主动杆系统的原理,叙述了结构上各个模块的组成,并简化系统,建立了各个模块的模型,应用仿真软件重点研究了控制主动杆的3种方法,即力控制、位置控制和速度控制方法。经过仿真分析,对比了3种方法的动态特性,应用PID算法,找出影响系统动态特性的关键参数,有效提高系统的快速性和稳定性。主动杆的应用使飞机具有更好的飞行品质,让飞行员拥有更友好的操纵体验,其广泛应用是未来趋势。
The artificial feel system provides necessary control feelings for pilots to control the aircraft,which is the main factor affecting the flight quality and performance.As people’s requirements for flight quality become higher and higher,it is particularly imperative to optimize the performance of the artificial feel system.Due to the active stick can regulate flight parameters in real time according to the flight state,it can effectively improve the handling qualities of the aircraft and become one of the research hotspots of the artificial feel system.Active stick is a control device that can regulate real-time characteristics such as force,displacement,damping,etc.,according to the flightstate of the aircraft.Compared with the passive stick,the most important feature of the active stick is the appication of the flight parameters to the force characteristic of the stick,which links the force perceived by the pilot to the flight status.This paper introduces the theory and composition of the active stick.We simplified the system,established the models for each module,and studied the three control methods of the active stick through simulation,including force control,position control and speed control.Through simulation analysis,we compared the dynamic characteristics of the three control methods.We also use the PID algorithm to find out the key parameters affecting the dynamic characteristics,which improved the system’s rapidity and stability.The application of the active stick makes the aircrafts have better flight quality and gives pilots a better handling experience.It will be widely applied in the future.
