Nano positioning platform low vibration movement

1. The nano positioning platform will vibrate during movement. In most cases, it will vibrate up and down. The main reasons for the vibration are piezoelectric ceramic expansion, mechanical material itself, mechanical assembly, movement speed, etc.;
2. The characteristics of the ceramic drive cannot be changed just like that. The materials and assembly can be improved to the best, but the speed is more difficult to control;
3. The speed control of the motion platform is mainly uniform speed and acceleration
4. The uniform velocity in the movement process has basically been achieved;
5. An effective solution to reduce motion vibration is acceleration control, especially in the starting phase of acceleration control is particularly important;
6. Although I have realized that different accelerations can be set to start at the starting stage, but this acceleration is not real or close to real acceleration, only the acceleration can be adjusted.
7. The nano positioning platform does require a low-vibration mode. I thought it would be simple, but the more in-depth research, the more I found that this is more difficult than the high-magnification subdivision algorithm;
