代码说明：

一、实验目的1、了解虚拟存储器的基本原理和实现方法。2、掌握几种页面置换算法。二、实验内容设计模拟实现采用不同内外存调度算法进行页面置换，并计算缺页率。三、实验原理内存在计算机中的作用很大，电脑中所有运行的程序都需要经过内存来执行，如果执行的程序很大或很多，就会导致内存消耗殆尽。为了解决这个问题，Window中运用了虚拟内存技术，即拿出一部分硬盘空间来充当内存使用，当内存占用完时，电脑就会自动调用硬盘来充当内存，以缓解内存的紧张。虚拟存储器是指具有请求调入功能和置换功能，能从逻辑上对内存容量加以扩充的一种存储器系统。它是采用一定的方法将一定的外存容量模拟成内存，同时对程序进出

基于非线性干扰观测器的直升机滑模反演控制
1、原论文及matlab仿真程序；2、提出一种基于非线性干扰观测器的滑模变结构控制方法。用一种非线性干扰观测器观测系统的不确定性和外界干扰，通过选择设计参数，可以使观测误差指数收敛。对引入非线性干扰观测器后的系统设计滑模变结构控制控制器，控制律的设计能够减小滑模抖震，保证闭环系统的稳定性，从而达到了对俯仰系统跟踪控制的目的。仿真结果表明，该方法能够较理想地观测干扰，减小控制器的输出，改善系统的控制性能。
