The servo control system of the servo motion control system Basic requirements

Require the ability to respond quickly: In order to ensure the high precision and low surface roughness of the contour cutting switch, in addition to the high positioning accuracy of the national exchange, the position servo system also requires good fast response characteristics, that is, the fast response of the tracking instruction signal is required.

The servo system of the CNC machine tool should meet the following basic requirements: 1 high accuracy; 2 good stability; 3 fast response, no overtuning; 4 wide speed regulation range; 6 low-speed large torque;6 The reliability of the system should be good.

Generally, there are the following requirements for the servo system: (1) High accuracy, and the servo system should have good positioning accuracy and contour processing accuracy. The positioning accuracy is generally 0.01-0.001mm, or even 0.1um. The accuracy of contour processing is related to the coordinated control of speed control and linkage coordinates.

The main performance requirements for the servo drive system of CNC machine tools are as follows: (1) The feed speed range should be large. It should not only meet the requirements of low-speed cutting feed, such as 5mm/min, but also meet the requirements of high-speed feed, such as 10000mm/min. (2) The displacement accuracy should be high.

The three basic requirements of the control system

The basic requirements of the automatic control system are stability, speed and accuracy. The system is in an equilibrium state before the disturbed action, and the system deviates from the original equilibrium state after the disturbed action. If the system can return to the equilibrium state before the disturbance disappears, the system is said to be stable.

The three performance indicators of the automatic control system are stability, speed and accuracy.The specific analysis is as follows: Stability: The constant value system requires that when the system is disturbed, it can return to the original expected value after a certain period of adjustment.

The requirements of the automatic control system are that various process conditions change during the production process. In chemical production, most of them are continuous production, and various equipments are interrelated.

After the equipment situation, it is necessary to control the on-site equipment or process to run the "tool" equipment according to the design requirements, such as valves, pumps, cylinders, solenoid valves, etc. belong to actuators; if the control scheme and hardware composition are available, then there should also be control scheme logic, which I understand is also a basic element.

Stability is the most basic requirement for the control system. When the system is disturbed, it will deviate from the original equilibrium state, but when the disturbance disappears,After a certain period of time, if the system can still return to the original equilibrium state, it is said that the system is stable. The accuracy of steady-state performance is a requirement for the steady-state performance of the control system.

What are the basic requirements for the automatic control system

1. The three performance indicators of the automatic control system are stability, speed and accuracy. The specific analysis is as follows: Stability: The constant value system requires that when the system is disturbed, it can return to the original expected value after a certain period of adjustment. Speed puts forward requirements for the form and speed of the transition process, which is generally called dynamic performance.

2. The answer is as follows: The performance requirements for an automatic control system are: speed, stability and accuracy. Speed refers to the speed of response control instructions.Stability means that the steady-state error after reaching the steady state should be acceptable. If it is not disturbed by the outside world, it will lose stability and enter an unstable state.

3. The given value changes according to the unknown time function, and the output is required to follow the change of the given value. Such as the radar antenna system that follows the satellite. The given value of the program control system changes according to a certain time function. Such as program-controlled machine tools. Editor This paragraph is widely used. The automatic control system has been widely used in all fields of human society.

What are the basic requirements for the control system

1. Analysis: The basic requirements for the control system can be divided into three words: stable, fast and accurate.

2. For the follow-up system, the controlled quantity always tracks the change of the parameter quantity.Stability is a basic requirement for the system. An unstable system cannot achieve the scheduled task. Stability is usually determined by the structure of the system and has nothing to do with external factors.
