摘　　要：随着控制技术的快速发展,众多学者与计算机工程实践人员采用线性的反馈控制方法对计算机系统的性能管理开展了大量工作。由于系统所处环境时刻变化,传统的线性控制方法显然已不能满足系统的性能需要,因此寻找一种适应于动态环境,并且在工程实践中比较容易实现的计算机控制方法是当前计算机性能管理面临的一个重要问题。文章以华为Fusion Server V5机架服务器为研究对象,设计出了一个基于线性参变模型(Linear-Parameter-Varying,LPV)的控制器以优化控制系统的性能,满足用户对服务器响应时间的要求。With the rapid development of control technology,many scholars and computer engineering practitioners have carried out a lot of work on the performance management of computer systems by using linear feedback control method.Because the environment of the system changes all the time,the traditional linear control method obviously can not meet the performance needs of the system.Therefore,it is an important to find a computer control method which is suitable for the dynamic environment and easy to realize in engineering practice.Taking Huawei Fusion Server V5 rack server as the research object,this paper designs a controller based on linear parameter varying(LPV)to optimize the performance of the control system and meet the user's requirements for server response time.
