三自由度直升机试验平台的控制

摘要三自由度直升机实验平台在直升机的有效模拟上有很好的作用。它作为自动控制中较为典型实验设备，在制导与控制理论教学与研究中是较为经典的物理模型。通过研究三自由度直升机系统，不仅能解决控制中的理论问题，还能将控制理论中的基础学科力学、数学和电学有机结合起来。从理论方法中得到经验，可以对真实的直升机系统亦或是其他工程系统设计者提供帮助。

本文着重研究了三度自由直升机实验控制平台上控制器的设计及稳定控制问题，在三通道数学模型建立的前提下，俯仰角、滚动角采用 LQR 线性二次型控制方法，偏航角采用 PID 控制实现直升机飞行姿态的稳定控制，以状态反馈法进行极点配置和参数调试并且以跟踪信号分析对比其控制稳定性，从而实现整个控制平台的有效姿态运行。77747

Title The control of three dof helicopter test platform

Abstract Three dof helicopter platform on the effective simulation of the helicopter has a good effect。As the typical experimental equipment automatic control, it's in the guidance and control theory in the teaching and research is also being bullish on classical physical model。By studying the three dof helicopter system, not only can solve the problem of control in the theory, also can be basic subjects in the control theory of mechanics, mathematics and electrical organic combine, in the three dof helicopter system in practical application。In a variety of control theory and the method of theory practice, especially in engineering, also there is a feasibility test questions, get experience from the theory and method, can the real helicopter system or other engineering designers to offer help。

This article focuses on the three degrees of freedom helicopter control platform controller design and stability control problem, on the premise of three-channel mathematical model is established, the pitch Angle and roll Angle LQR theory is adopted linear quadratic control method, the yaw Angle of the stability of the helicopter flight control is realized by using PID control, by the method of state feedback pole assignment and tuning parameters and to track the signal analysis comparing the control stability, so as to realize the effective posture of the entire control platform to run。

Keywords Three degrees of freedom helicopter PID controller LQR controller Attitude control
