Abstract
In this work, the probleU of controlling and following up the execution of large imdustrial projeots and procesmm ilsstudied . Each of these projects or processes oonsists of a number of sub-projects and sub-prooesses which oontain different oontinuous manufaoturing (processing) lines. The problem is treated as a feedbaok oontrol problem. The industrial jobs of the project (prooess) as well as the relations between them are expressed mathematioally. A dynamio model tdth a decentralized controlstructure, which is more practical and realistic, is derived.
Decentralised control theory is applied to the proposed model.
Two approaahes are oonsidered. In the first approaoh, the gr~ of managers and engineers oontrolling the execution of eaoh sub-project (sub-process) is trated as a decentralized oontroller and the dynamio funotions of this group are expressed mathematically. The poles of the olosed loop system are arbitrarily assigned such that responses agreeing with the plan requirements are attained. In the second approaoh, plan tasks optimization is considered, and a sub-optimal decentralized oontrol law is applied .. This oontrol law has a bounded sub-optimality index. The two approaches are illustrated by a ’numerical example. It has been found that eaoh sub-projeot (sub-process) oontroller oan oontrol his own sub-system irrespective of the other sub-systems responses. Finally, it was shown that standard responses oan be plotted for each projeot (process) to suit the different oircumstanoes of the execution the mathematioal equ”tions required for the calculation of the oorrective forces, have been derived.
