ABSTRACT:
An electro-hydraulic positioning system which has automatic calibration capabilities is disclosed. The system includes a microprocessor which accesses calibration parameters stored in a non-volatile memory unit. The microprocessor adjusts the position demand according to the stored calibration parameters. The system may be placed in an atuomatic calibration mode. In which case, update calibration parameters are automatically determined and stored. The system also includes a microcontroller which monitors system operating variables and reports deviations of the variables from expected values for same.
