Where is the position detection device of the semi-closed-loop control system installed
on the moving parts of the machine tool.The position detection device of the closed-loop control system is installed on the moving parts of the machine tool. For semi-closed-loop control CNC machine tools, the detection device can be installed on the screw or motor shaft to monitor and feedback the location information of moving parts.
It can be installed on the screw nut or the workbench of the nut link.
Semi-closed-loop control numerical control system Fully closed-loop control numerical control system: the position detection device is installed on the machine tool workbench to detect the actual operating position (linear displacement) of the machine tool workbench, and compare it with the instruction position (or displacement) calculated by the CNC device, and control it with the difference. Its control block diagram is shown in Figure 1-12.
The position detection device of the closed-loop control system is installed on the moving parts of the machine tool. Comparison between the open-loop control system and the closed-loop control system: the structure is different.The open-loop control system is generally simple in structure, which is suitable for situations where the control accuracy requirements are not high and the components of the system itself are relatively stable.
The position detection component is installed at the shaft end of the motor or the screw shaft, and the actual operating position of the machine tool workbench is indirectly calculated by measuring the angular displacement. Closed-loop control: Feedback the position signal of the workbench through the grating ruler. The feedback accuracy is higher than that of the semi-closed loop, but it is unstable. If the gap between the intermediate links is large, there will be vibration.
The difference between the closed-loop control system and the semi-closed-loop control system is
1. Closed-loop control The difference between the system and the semi-closed-loop control system is that the sensors used are different.
2. The semi-closed-loop control system can obtain higher control accuracy than the open-loop system, but lower than the closed-loop system; compared with the closed-loop system, it is easy to achieve system stability. At present, most CNC machine tools with general precision adopt this semi-closed-loop control feed servo system to reduce manufacturing costs.
3. Feedback control difference: the closed-loop feed servo system uses feedback sensors toMonitor the actual position, speed or force in real time, and adjust according to the feedback information to make the actual value close to the expected value.
4. The position detection point of servo systems such as semi-closed-loop feed servo system is derived from the drive motor (commonly used AC and DC servo motor) or the screw end. By detecting the rotation angle of the motor and screw, the displacement of the workbench is indirectly detected, rather than directly detecting the actual position of the workbench.
5. Semi-closed loop is mostly used in the servo motor control system, and a small number of stepper motors also have this control method. The motor itself has encoder feedback, and the encoder signal is connected to the driver, that is, the driver and motor are directly closed-loop control.
What is the principle of the semi-closed-loop control system?
1. Closed loop: Compare the measured value of the system output with the expected given value, thus generating a deviation signal. This deviation signal is used for adjustment and control to make the output value as close as possible to the expected value.
2. [Answer]: The semi-closed-loop control system does not directly measure the displacement of the workbench, but measures the corner of the servo motor through the corner detection components related to the servo motor, such as the photoelectric encoder, calculates the actual displacement of the workbench, and feedbacks it to the computer for comparison. The difference is controlled.
3. If you only ask the principle, the answer is very simple, feedback the principle.
4. The numerical control systems generally used in schools are open-loop servo systems, because they are very cheap.
5,Semi-closed-loop servo system: The feedback control system that keeps the output and the expected value consistent in operation is often called an automatic adjustment system, while the feedback control system used to accurately follow or realize a certain process is called a servo system or follow-up system.
The main difference between the closed-loop feed servo system and the semi-closed-loop feed servo system is
1. The difference between feedback control: the closed-loop feed servo system uses feedback sensors to monitor the real-time The position, speed or force of the interval, and adjust it according to the feedback to make the actual value close to the expected value.
2. The main difference between the fully closed-loop feed servo system of CNC machine tools and the semi-closed-loop feed servo system is the installation position of the feedback unit.
3. Different characteristics. The closed-loop servo system has high positioning accuracy, but the system is complex, difficult to debug and maintain, and the price is relatively expensive. It is mainly used for high-precision and large CNC machine tools. The semi-closed-loop feed servo system has a simple structure, convenient debugging and high accuracy, so it has been widely used in modern CNC machine tools.
4. The main difference between the closed-loop feed servo system and the semi-closed-loop feed servo system is the detection unit. According to the relevant public information of the query, the main difference between the closed-loop feed servo system and the semi-closed-loop feed servo system is the detection unit, CNC boring and milling processing, and the tool radius compensation is not used during the processing of the detection unit.
5. The detection position is different. Open-loop system: do not feedback the results of the control to affect the current control. Closed loop: closedRing monitoring is the final execution link of the whole system, which can be said to compensate for the errors caused by any part of the system.
6. Refers to different full-closed-loop servo systems: send part or all of the output of the control system back to the input terminal of the system through certain methods and devices, and then compare the feedback information with the original input information, and then apply the comparison results to the system for control to avoid the system deviating from the predetermined Goal.
