Abstract

A computer-controlled system is a synergistic coupling of the controlled process and the controller computer. The authors have defined new performance measures for real-time controller computers based on this coupling. They present a systematic study of a typical critical controlled process in the context of new performance measures that express the performance of both controlled processes and controller computers (taken as a unit) on the basis of a single variable: controller response time. Controller response time is a function of current system state, system failure rate, electrical and/or magnetic interference, etc. , and is therefore a random variable. The controlled-process chosen for study is an aircraft in the final stages of descent, just prior to landing. Control constraints are particularly severe during this period, and great care must be taken in the design of controllers that handle this process.
