Abstract

Controlling a system with a computer offers some advantages and a few drawbacks too. Intelligent application of computer control seeks to exploit the strengths and minimize the deficiencies of the computer as a controller. One advantage of computer control is the ability to build into software at a low cost some control features that might be expensive if done in hardware. A characteristic of computer control that at certain times could cause difficulties is the sampling process used in sensing variables and positioning actuators. One of the important pitfalls to avoid in applying computer control to thermal and mechanical systems is instability due to the sampling operation.
