Application of individual channel design to server control

Abstract

There has been lately interest in the application of control theory to computing systems. Applications, such as, in cyber physical systems, demand study of the dynamic performance of computing systems under load and other disturbances. This paper addresses an important problem of feedback control of a computer server system. Considering a 2x2 server control system, individual channel design approach allows independent controller design of server utilization and average waiting time control loops. Simevents in Matlab is used to simulate, in a novel way, the physical server on which the feedback architecture is imposed. Simulation results are provided to validate the proposal of diagonal control of computer server together with demonstration of its robust performance.
