How does Manhart (Guangdong) CNC Machine Tool Co., Ltd. optimize the control algorithm and parameter settings of servo motors to improve bending efficiency?

Optimizing the control algorithm and parameter settings of servo motors is a key step in improving bending efficiency. Here are some suggestions:
1、 Control algorithm optimization
1. Introduce advanced control algorithms, such as fuzzy PID control, adaptive control, etc., which can adaptively adjust according to the real-time state of the system, thereby improving control accuracy and response speed.
2. Increase sampling rate: Reduce delay in the control process, enabling the system to respond more quickly to changes, thereby improving bending efficiency.
2、 Parameter setting optimization
1. PID parameter tuning: The performance of a PID controller largely depends on the selection of parameters. Modern optimization algorithms such as genetic algorithm, particle swarm optimization algorithm, etc. can be used for parameter tuning to obtain more accurate parameters and improve the control accuracy and stability of servo motors.
2. Feedback optimization: In order to improve the response speed and stability of servo motors, speed or acceleration feedback can be introduced and combined with filters for optimization. In addition, improving the resolution of the encoder, reducing system noise, and optimizing the filter of the feedback system can all improve the accuracy of the feedback signal, thereby improving the accuracy and stability of control.
3. Nonlinear compensation: There are nonlinear factors in servo motor systems, such as backlash, friction, etc. To reduce the impact of these nonlinear factors on control performance, nonlinear compensation methods such as feedforward control and adaptive control can be adopted.
Specifically, the following parameters can be set:
1. Position feedforward gain: The larger the set value, the smaller the position lag, and the higher the high-speed response characteristics of the control system. However, it should be noted that excessive feedforward gain may cause system position instability and oscillation.
2. Speed proportional gain: The larger the set value, the higher the gain and stiffness. It is necessary to determine the appropriate setting value based on the specific servo drive system model and load value.
3. Speed integration time constant: The smaller the set value, the faster the integration speed. This helps the system to respond more quickly to speed changes.
4. Speed feedback filtering factor: The larger the value, the lower the cutoff frequency, and the smaller the noise generated by the motor. This helps to reduce noise interference and improve control stability.
3、 Other optimization measures
1. Reduce mechanical transmission errors: Optimize the mechanical structure, reduce friction and clearance during the transmission process, reduce transmission errors, and thereby improve the accuracy of feedback signals.
2. Debugging and testing: After completing algorithm and parameter optimization, it is very important to conduct sufficient debugging and testing. This includes verifying the stability, response speed, and bending accuracy of the control algorithm. By continuously adjusting and optimizing, find the most suitable control algorithm and parameter settings for the current application scenario.
In summary, by comprehensively applying the above optimization measures, the control accuracy and response speed of the servo motor can be effectively improved, thereby improving the bending efficiency. It should be noted that specific optimization measures and parameter settings should be adjusted and optimized according to actual application scenarios and bending needs.
