Develop excavator control and measure system based on LabVIEW The control of an excavator is difficult from the standpoint of the following problems: parameter variations in mechanical structures, various nonlinearities in hydraulic actuators and disturbance due to the contact with the ground. Apply NI LabVIEW to control and measure excavator hydraulic system, and monitor flaw, pressure, temperature and position of actor cylinders. The control strategy and algorithm are simulated using MATLAB control system toolboxes, MATLAB Script is directly transplanted intoLabVIEW, and the physical simulation of excavator is accomplished. |
