An Investigation of a Digital Electrohydraulic Servovalve.
Abstract
This report describes the investigation of an electrohydraulic actuator which uses a digital servovalve control. The digital servovalve uses poppet solenoid valves and fixed orifices to replace the flow control functions of the conventional electrohydraulic analog servovalves. The digital servovalve configuration allows direct digital control of the direction and rate of an actuator used with the digital servovalve. The report describes the hardware fabricated for the investigation, some theoretical limitations of the technique and the test results from performance measurements made on the mechanization. The investigation was successful in demonstrating the validity of the concept and the performance characteristics of an example mechanization. (Author)
