Abstract
The objective of this research project was to build a closed-loop hydraulic motion control system with a LabVIEW- based digital controller. The system consists of a weighted sled that moves along two parallel, horizontal guides, an electrohydraulic actuation system, a sensor for measuring the position of the sled, and a LabVTEW-based, closed-loop control program. A phase-lead compensator was implemented into the control program to demonstrate the capabilities of the motion control system. The continuous design was accomplished by developing transfer function using system identification and control computations available in MATLAB. The corresponding discrete compensator was modeled in SEVIULINK to evaluate its performance with a continuous closed - loop actuation system. The compensator was then incorporated into an existing LabVIEW code for closed loop control. The assembled system was used to demonstrate the effects of using a compensator and change in sampling rate on the performance of the motion control system. Experiments were performed to identify system parameters which would ensure optimum response in spite of using a proportional directional flow control valve.
