摘要
针对直升机动力学表现出的高阶,强耦合的特点,本文基于一拍跟踪的原理,设计了显模型跟踪解耦控制系统,开发了控制阵,为提高系统动态和稳态性能,对系统参数进行了优化,数字仿真表明,模型跟踪解耦性能良好,同时可以迅速改变显模型,以达到改变操纵特性的目的,文章最后对如何选取采样周期及显模型带宽进行了讨论。
The typical characteristics of a helicopter is high order dynamics, strong couplings. In this article, A model following control system was designed. The explicit model was a linear, decoupling modd such that the pilot commanded pitch attitude with the longitudinal cyclic, roll attitude with the lateral cyclic, yaw rate with the pedals, and Earth-fixed vertical velocity with the collective. In order to improve the following performance, the control law was optimized. Simulations show that satisfactory performance can be achieved. In the end, how to select the sample the sample time and the model bandwidth were discussed.
