Experimental Study on Active Vibration Control of Flexible Manipulator Based on Improved PPF Algorithm

Abstract:

The positioning accuracy and work efficiency of flexible manipulator is seriously affected by its vibration. Therefore, vibration control of single joint flexible manipulator is studied by using an improved PPF algorithm based on LabVIEW and piezoelectric technology. Firstly, the improved PPF algorithm principle is introduced. Then, the experiment process is discussed in detail. Experimental result shows that the improved PPF algorithm can effectively control the first two modal vibration of flexible manipulator. The control effect is close to 14 dB and improved nearly 4.5 dB compared with PPF algorithm.
