description An electro-hydraulic positioning system, which has automatic calibration capabilities, includes a microprocessor (52) which accesses calibration parameters stored in a non-volatile memory unit (56). The microprocessor (52) adjusts a position demand according to the stored calibration parameters. The system may be placed in an automatic calibration mode, in which case updated calibration parameters are automatically determined and stored. The system includes a microcontroller (32) which monitors system operating variables and reports deviations of the variables from expected values thereof.
