FULL-SCALE EXPERIMENTS OF CONTROL SYSTEM FOR A HYDROFOIL CATAMARAN

The Hydrofoil Catamaran (HC) concept was developed based on tank test. In 1990, prototype HC named EXCELLER was built and sea tests were conducted. The EXCELLER has flaps and ailerons for pitch, heave and roll control. This paper describes the Roll Stability and Control Augmentation System (Roll SCAS) using ailerons, and its validation at sea. The NEC-PC 32 bit computer was installed on the ship to form the data acquisition and the digital control system. The dynamics of the actuators and the ship were obtained by measurement of the actual hardware. Roll angle and roll rate were used as feedback variables with gains.
