Of Micros and Men in Control

Surveys of industry are not new; neither are the complaints that industry is technologically backward and that graduate courses do not match industrial needs. The gap between theory and practice in feedback control is well known and various attempts have been made to defme it and reduce it. It was with these and related matters in mind the introduction of microprocessors and microcomputers (from here on termed micros), the level of instrumentation, maintenance problems, training of staff and management structures that the survey was conceived and implemented. Twenty-two companies were visited across a spectrum of manufacturing industry, the selection of which is explained below. The survey proved of considerable value from several aspects and could usefully have been extended.
