NONLINEAR COMPENSATION OF THE HYDRAULIC SERVO FOR THE VALVE-ORIFICE NONLINEARITY.
Abstract
A nonlinear compensation loop employing square root and division networks is tested for its ability to eliminate the effects of the valve-orifice nonlinearity in a hydraulic servo. An analog simulation illustrates the feasibility of the compensation loop and the loop is implemented in a hardware test. Test inputs to the system are triangular, sine, and square waves of 2 degrees and 10 degrees amplitude at 0.1 and 0.5 Hz. The effectiveness is evaluated by comparing the loaded-compensated and loaded-uncompensated responses to the unloaded responses. For most cases, the loaded-compensated responses are identical to the unloaded responses. (Author)
