ABSTRACT:
An automatic trim circuit for hydrofoil craft which compensates for offsets in the system due to manufacturing and assembly tolerances and wear of parts. This is achieved by integrating an error signal derived by comparison of a reference signal with an actual position signal and applying the integrated output, after amplification, to one or more servo systems which actuate the control surfaces of the hydrofoil craft.
