Process control by personal computer

This article covers the operation, design procedures and the applications of a microcomputer-based digital dynamic control system (d.d.c.) and underlines how the addition of a simple analogue interface on a small personal computer allows the designer to be come familiar with the digital dynamic control techniques in a real (not simulated) environment. The system described consists of an eight multiplexed input a-to-d converter, a d-to-a converter with power outputs and a six input adder. Thus multiple feedback controlling only one output variable is possible. Alternative interfaces are also described; their object is acquiring data and simplifying the software which the microprocessor needs to make data conversion.
