Özet:
In this thesis, swash plate active vibration control techniques were investigated utilizing the weight-limited multi-frequency two-weight notch LMS filters to achieve swash plate vibration reduction and pump noise reduction. This research also includes direct swash plate acceleration measurements, case acceleration measurements, and simultaneous multi-position microphone measurements in the semi-anechoic chamber. Simulation studies of the high fidelity pump control system model including realistic swash plate moments are presented to demonstrate the feasibility of the swash plate active vibration control. A 75 cc/rev swash plate type axial piston pump was modified to implement a fast dynamic response pump control system which is required for canceling swash plate vibration. A high speed real-time controller was proposed and realized using NI LabView Field Programmable Gate Array (FPGA). Vibration and noise measurements using a tri-axial swash plate acceleration sensor, two tri-axial case acceleration sensors, and three microphones were conducted in the semi-anechoic chamber at Maha fluid power research center of Purdue University to show the influence and effectiveness of the proposed swash plate active vibration control algorithm.
