摘要：AbstractIn this paper, similarities and differences between control and management theories are discussed. The concepts of control, regulator/controller, and command are defined and compared. Model reduction is described and divided into three types. The necessity to consider a control subject for solving automatic control problems is pointed. A three-stage cycle for control analysis and design is proposed: analysis of the physical system; mathematical model design and control analysis; control design.
