Automatic Control Theory originated in the 19th century, during the second half of it, and carried the name "regulation".With the extension of the application of machines with steam engines there is a need for special adjustments, is a device that supports uninterrupted operation of these machines.This fact gave impetus to start research in the area of technical facility management and is known as the "theory of automatic control."In the future, scientists have deduced the main aspects of the teachings quite well can be applied in systems such as social and economic.Therefore, the original name was changed to the term the broad meaning - "Automatic Control Theory".
The next step in this field of research is the process of implementation of the control system (CS), and devices for automatic regulation of certain electronic components and remote control.This fact contributed to the emergence of sufficiently accurate guidance systems and tracking, telemetry and remote control, automatic correction and control.20th century (50th year) is famous for the creation of automatic control systems of industrial complexes and production processes with the use of electronic computers.
any object management means exposure to it to achieve the goals defined by the specific process or condition.As an object of control (OC) can be adopted motor, any machine or aircraft.The use of technical means without the involvement of a person in the process of management is called automatic.In turn, the automatic control system (ACS) is based on pooling of automatic control and Conditions.
Fundamentals of control theory suggests maintaining law changes certain physical quantities that characterize the processes occurring in the OC, without human intervention.These values are called "manageable size."In this class, you can see the systems of automatic control.Their task is to establish constant values of the control value.It is also necessary to achieve the changes of the same magnitude within a given program.For example, when considering the baking oven as an object of management and as a controlled quantity will serve as the temperature which varies its value for a particular program, based on the requirements of the process.
Further studies aim control communicates directly with a set of quality indicators that give a complete characterization of the system.In turn, these indicators began to be required for the achievement of the smallest or largest (limit) values.It is for this and created self-adapting or adaptive systems.
Automatic Control Theory helps to improve the functioning of the object to be controlled by a special system.Often, these auxiliary operations such as start-up, control, stop and adjustment can also be automated.By itself, the ACS should function as part of a specific production facility.
Theory of automatic control systems of classification consider such controls as:
- management objective;
- type of the control loop;
- signaling method.
Theory of automatic control laws should study the processes occurring in the construction of self-propelled guns, explore the structural features of the object management with regard to the conditions of his work for the construction of high-quality, precise and workable control systems.
