摘要
倾转旋翼飞行器是一种兼具固定翼飞机和直升机双重飞行模式的新概念飞行器。倾转旋翼模型实验台作为航空领域中进行模拟、仿真、测试的关键设备,在倾转旋翼飞行器的研制过程中起到重要作用。它可以真实地模拟倾转旋翼飞行器在空中的各种飞行姿态,再现其运动时的动力学模型,从而对倾转旋翼飞行器的各分系统及其相应器件的性能进行模拟测试,检验被测系统或部件是否达到倾转旋翼飞行器的性能指标。
本课题以我校直升机旋翼动力学国防科技重点实验室设计的倾转旋翼模型实验台为研究背景,对其旋翼模型伺服系统的设计与实现进行研究。
本文首先分析和研究了倾转旋翼模型实验台的结构和功能,根据实验台对旋翼操纵伺服系统的技术要求,设计了一套电动旋翼操纵伺服系统,克服了原有电液伺服系统高温不稳定、体积大、系统复杂等缺点。
通过对实验台旋翼模型伺服系统的研究,建立和分析了旋翼模型伺服系统的数学模型,采用永磁同步直线电机作为执行元件,运用常规PID控制+前馈控制方法,实现了对旋翼模型作总距操纵和横向、纵向周期变距操纵,并根据结构不变性原理对由旋翼运动产生的动态载荷提出了补偿方法。
最后,应用面向对象技术,基于Windows平台的VC++6.0开发环境编写了系统测控软件,实现了系统的自检、初始化,旋翼桨距的控制,变换矩阵和试验数据的显示、存储和打印等功能,满足了系统对测控软件的要求。
Tiltrotor vehicle is a new concept of aircraft which is the combination of rotor aircraft and wing aircraft. In the aerospace research field, tiltrotor model bench plays important roles in the research and development of tiltrotor vehicle.It can simulate all kinds of tiltrotor vehicle stance and reappear its dynamic characteristice, so that the performance can be tested by simulation of tiltrotor vehicle’s subsystem and its related components; the bench can also check whether the systems or the components can fulfill the whole design performance.
The dissertation takes the tiltrotor model bench as object, and studies the design and realization of the rotor model servo system.
First of all, according to the technical indicators of the bench, an electromotion scheme of the servo system is designed. It replaces the electrohydraulic servo system and overcomes the shortcomings of the electrohydraulic servo system.
Secondly, by establishing and analyzing the tiltrotor model bench, the rotor model operation which used to drive rotor for the collective pitch control and the cyclic pitch control on the tiltrotor model bench is achieved .The PMLSM is used as an actuator, and the PID control and the feedforward control is taked.a compensation method for dynamic load which is caused by rotor rotation is presented base on structure-invarient theory.
Finally, the test control software is designed using C++ language.This software can realize these functions: system self-check, system initialization, rotor pitch control, display and save of transform matrix, document print etc.
