Abstract
A system and method for remotely measuring and linearizing flow characteristics, specifically velocity characteristics, of an electrohydraulic servo valve and actuator system. A plurality of raw command signals are generated in sequence, and corresponding motion data at the valve and load (including the actuator) are measured and stored. A linearized characteristic is then generated corresponding to the range of motions measured, and a look-up table is generated which relates raw command signals to command signals necessary to obtain the desired linear motion characteristics.
