What are the examples of automatic control principle and open-loop control in the system in life?

The principle of automatic control is actually that after the machine starts, it rarely intervenes in its work manually. The machine can run the pre-arranged work order by itself. The so-called open loop means that the input does not monitor the work of the output after work, but relies on the self-check of the output to control the work.

Generally speaking, the open-loop system does not have "automatic control", but the closed-loop system does. Take the example of daily life, using electricity to boil water -- the temperature problem.

Open-loop control system: If there is no feedback loop between the output and input of the system, the output will not affect the control effect of the system, and the system becomes an open-loop control system. The original CNC machine tool feed system is an open-loop control system, which commands the computer control system and drives the stepper motor movement.

Through automatic control to optimize the setting of traffic lights, adjust the take-off and landing time of the aircraft, control the vehicle flow, etc., the smoothness and safety of traffic have been greatly improved. Let's look for traces of smart home. Automatic control theory plays an important role in the family, allowing us to have an intelligent life.

The course of learning the principle of automatic control and its application can be applied to many aspects of life, such as home automation: smart home, automatic washing machine, automatic feeder, intelligent door lock and other equipment, which can realize intelligent control and management through the principle of automatic control.

What are the examples of automatic control systems?

The automatic control systems in daily life include recorders, air conditioners, refrigerators, water heaters and electric blankets. The recorder automatically rewinds; in fact, its playback process is also automatic, which is a kind of program control. The air conditioner automatically adjusts the indoor temperature, humidity and other indicators. The electric refrigerator mainly adjusts the temperature automatically.

Automatic control system case: Case 1: Temperature alarm control In industrial situations, temperature is the most involved parameter. When the temperature is high, stop heating, and when the temperature is low, start heating, or finally stabilize the temperature at about 100℃. These seemingly simple temperature controls are widely used in industrial occasions.

Voice-controlled lamp. Voice-controlled lamp is a kind of voice-controlled electronic lighting device, which is composed of an audio amplifier, a frequency selection circuit, a delayed turn-on circuit and a controllable silicon circuit.

There is a storage tank. When the liquid level is below the lower limit, water needs to be poured in, and when it is higher than the upper limit, it needs to be drained out.

This is the classical control theory based on transfer functions, which mainly studies the analysis and design of linear constant systems with single input and single output. Open-loop control in the system: all manual control, most of the program control and CNC machine tools, and time program control belong to open-loop control. For example: the switch of lighting.

What are the examples of closed-loop automatic control in life?

1. [Answer]: The open-loop control system includes: induction cooker, microwave oven, printer, etc. Closed-loop control systems include: electric refrigerators, flush toilets, rice cookers, etc.

2. For example: automatic temperature control of the air conditioner, when the ambient temperature is higher than the set temperature, the air conditioning refrigeration system automatically turns on and adjusts the room temperature to the set value. Working principle: Closed-loop control has a feedback link, through the feedback system isThe accuracy of the system is improved and the response time is shortened, which is suitable for systems with high response time and stability requirements for the system.

3. Generally speaking, the open-loop system has no "automatic control", but the closed-loop system has. Take the example of daily life, using electricity to boil water -- the temperature problem.

4. In daily life, many control systems can be understood as open-loop control systems. For example, the speed of the electric fan is determined by the inner gear and cannot be automatically adjusted according to the ambient temperature. Closed-loop control system: Feedback control system is also known as closed-loop control system. The output has a direct impact on the control effect. Working principle: Closed-loop control has feedback links.

5. The automatic water heater of the water tower is also a simple closed-loop system. When the water has reached the lower limit, the sensor informs the motor to start and pump water to the water tower;When the water is full and the upper limit is reached, the sensor controls the power to off and maintain it. A common feature of a closed-loop system is that it has feedback links, otherwise it cannot constitute a closed loop.

6. Machines with closed-loop control systems include: household refrigerators, air conditioners, rice cookers and washing machines; while machines with open-loop control systems include: ordinary lathes, flush toilets, multi-speed electric fans, dimming table lamps, and high-rise water tanks. The main judgment method should start from the definition of closed-loop control and open-loop control.

What are the components of an automatic control system?

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

2. The automatic control system is mainly composed of four links: controller, controlled object, actuator and transmitter. The research on automatic control technology is conducive to freeing human beings from the complex, dangerous and tedious working environment and greatly improving control efficiency. Automatic control is a branch of engineering science.

3. It consists of three parts: executive components, measurement components and control components.
