Automatic control system. An automatic control system (ACS) sustains or improves the functioning of a controlled object. In a number of cases the auxiliary operations for the ACS—starting, stopping, monitoring, adjusting, and so on—can also be automated. An ACS functions mainly as a member of a production or some other complex.
