PID Control of a Parallel Vibration Isolation System Based on Pneumatic Artificial Muscle

Abstract:

In the ultra precision measuring and machining, precision measuring instruments and precision accuracy are not only related to the precision of the instrument itself, the vibration from the surrounding environment, and many other factors also determine the accuracy of the measurement and processing. In order to solve the micro-amplitude vibration and shock proof problem of high precision equipment, the article adopted the active vibration isolation technology to build the vibration isolation experiment system based on the pneumatic artificial muscle as the action, according to the characteristics of the vibration isolation system and performance requirements, The experiment was completed by using PID control algorithm. By comparing with passive control, the results show that the vibration isolation system has good broadband vibration isolation effect, in the low frequency, effect is remarkable. This study laid a foundation for further control of pneumatic muscle in isolation system.
