The meaning and characteristics of the control system

The meaning of the control system is composed of the control subject, the control object and the control media with its own goal. And the functional management system. It is characterized by systematic, feedback, adaptive and expected.

Control system refers to a management system with its own goals and functions composed of control subjects, control objects and control media. Features The control system has strong environmental adaptability, the control system has its own purpose, and the control system has strong feedback function.

The system structure is reasonable (that is, the structure is scattered). The input and output data of the system are processed or selected in advance through the subsystem, and the data transmission volume is reduced, which reduces the load of the microcomputer and improves the control speed. Due to the reduction in the amount of information, programming is simple, and it is very convenient to modify and change.

What is the function of the control system?

1. The part used to control the normal and reliable flight of the carrier rocket along the predetermined orbit. The control system consists of three major parts: guidance and navigation system, attitude control system, power supply and distribution, and timing control system.

2. The function of the control system is to determine the optimal injection amount of gasoline according to the operation of the engine and the operation of the vehicle.

3. Tracking anti-skid control system (TCS): the main function of TCSIt is to prevent the driving wheel from slipping when the car starts, accelerates and brakes on slippery roads, and improves the stability, acceleration and climbing ability of the car.

4. Electrical control system refers to the combination of a number of electrical originals to realize the control of one or some objects, so as to ensure the safe and reliable operation of the controlled equipment. Its main functions are: automatic control, protection, monitoring and measurement.

5. The body electronic control system actually includes automobile safety, comfort control and information communication system. It is mainly used to enhance the safety, comfort and convenience of cars. Enhance car safety, such as: airbags, seat belts, central anti-theft door locks; enhance car comfort, such as: adaptive air conditioning, seat control, etc.

6. Third, the relevant electronic control system of the car can provide a role for the power performance, economic performance and emission performance of the car.Better improve the fuel economy of the vehicle engine and the best working condition of the related engine.

Please briefly explain the composition of the control system

1. Please briefly explain the composition of the control system. Correct answer: The control system is composed of the controlled object and the control device. In general, the control device consists of: measuring components, ratio Comparative components, amplification components, actuators, correction devices, given components are composed, among which measuring components, comparison components and actuators are indispensable.

2. The automatic control system is mainly composed of four links: controller, controlled object, actuator and transmitter. Controller: The wiring of the main circuit or control circuit and the resistance value in the circuit can be changed in a predetermined order to control the start-up, speed regulation, braking and reverse master command device of the motor.

3. The computer control system consists of two parts: computer and industrial objects, including hardware and software. Computer control system refers to the use of a computer or digital controller device to realize the function of the controller in the automatic control system.

4. The automatic control system is mainly composed of four links: controller, controlled object, actuator and transmitter. Composition of automatic control system Controller: At present, the controller of the control system mainly includes PLC, DCS, FCS and other main control systems.

5. The automatic control system is composed of a controller and a controlled object. However, to achieve complex control tasks, a typical automatic control system should usually include: fixed components, execution components, measurement transmission components and comparison components. According to the different control principles, the automatic control system is divided into open-loop control system and closed-loop control system.

6. Sensor Sensor is the "eye" and "ear" of the electronic control system. It converts various physical parameters that reflect the working condition and state of the engine, the driving condition and state of the car into electrical signals and transmit them to the electronic controller.
