【Abstract】 An adaptive active controller is used to drive the compressor of a pulse tube cryocooler. The 50 Hz micro-vibration force of the pulse tube cryocooler is reduced from 0. 21 N to 0. 05N, and the 100 Hz micro-vibration force is reduced from 0. 26 N to 0. 04 N, the 150 Hz micro-vibration force is reduced from 0. 9 N to 0. 04 N, the 200 Hz micro-vibration force is reduced from0. 97 N to 0. 02 N, and the 250 Hz micro-vibration force is reduced from 0. 69 N to 0. 06 N, the test results show that the adaptive active vibration control has obvious effect on the first five harmonics vibration reduction of the compressor.更多还原
