说明：  关于预测控制的MATLAB-s-function模块编写。 网络化控制系统是一种通过网络实现传感器，控制器和执行器之间数据交换的分布式实时反馈控制系统。其应用领域广泛，包括过程工业，航天工程，运输管理，机器控制，远程手术，智能家居等。具有长距离数据交换与共享，成本低, 便于安装和维护，高灵活性和可靠性，易于重配置及高移动性等优势。同时，由网络化控制系统引起的网络诱导时延和其共享、开放、可进入等特点对系统稳定性和安全性造成的影响也不可忽略。故本文设计了一种网络化预测输出跟踪控制系统以解决网络时延问题，并站在安全的角度研究虚假数据注入攻击问题(MATLAB-s-function.Networked control system is a distributed real-time feedback control system that realizes data exchange among sensors, controllers and actuators through network. Its applications range is wide, including process industries, aerospace engineering, transportation management, machine control, remote surgery and smart homes.)
