Due to the requirement of ship model hydrodynamic testing with the rudder swinging, a high-frequen-cy steering machine as well as synchronous force-measuring system are developed. The measurement and con-trol system applies the "PC + motion control card + data acquisition card", and is based on the principle of vir-tual instrument technology platform. It is not only used for the conventional model-scale hydrodynamic testing with a constant rudder angle, but also makes the rudder swinging according to the predetermined curve. Further more, it can simultaneously measure the force acting on the rudder during test. The application of the system shows the excellence of the measurement and control performance, and the system can be easily built, common-ly used and highly integrated, also has a good hunman-eomputer interaction.
