The application of digital techniques to process automation started in about 1960, when the first process computer was installed. From about 1970 process computers with cathodic ray tube display have become standard equipment for larger automation systems. Until about 1980 the annual increase of process computers was about 20 to 30%. The cost of hardware has already then shown a tendency to decrease, whereas the relative cost of user software has tended to increase. Because of the high total cost the first phase of digital process automation is characterized by the centralization of many functions in a single (though sometimes in several) process computer. Application was mainly restricted to medium and large processes. Because of the far-reaching consequences of a breakdown in the central computer parallel standby computers or parallel back-up systems had to be provided. This meant a substantial increase in cost. The tendency to overload the capacity and software problems caused further di | | 出版日期 | Textbook 1991Latest edition | | 关键词 | Markov; Regelungstheorie; algorithms; computer; control; control system; control theory; design; mechanical | | 版次 | 2 | | doi | https://doi.org/10.1007/978-3-642-86420-9 | | isbn_softcover | 978-3-642-86422-3 | | isbn_ebook | 978-3-642-86420-9 | | copyright | Springer-Verlag Berlin Heidelberg 1991 |
