摘要
三自由度直升机实验平台包含了一个典型的高阶次、不稳定、多变量、非线性和强藕合控制系统本文研究分析了三自由厦直升机控制系统的数学模型，介绍了线性二次型最优调节器（LQR）的基本原理，并针对直升机控制系统的平衡控制问题，设计了线性二次型最优调节器（LQR），以实现对三自由度直升机的最优控制，MATLAB仿真实验结果表明了该方法有较好的控制效果。
Three DOF Helicopter experimental platform comprises a typical control system with the feature of high order, instability, multivariable, non-linearity and tight coupling. This paper analyses its mathematical model and introduces the basic principle of the LQR optimal regulator as well as designs the LQR for the balance control of the Helicopter control system, and realizes the optimal control of three DOF Helicopter. The MATLAB simulated experiment result indicates that above method has better control effect.
