Abstract:

Hardwareintheloop system is designed according to the demands of study and design. In the system, computer model simulators on ship motion and sea environment, fullscale controller and fullscale operation terminal are implemented and 3D ship motion is shown by a 3D simulator based on DirectX. A fullscale controller has the same network interface, signal input/output interface with the practical controller used in the ship. Validated simulation can be taken using the hardwareintheloop simulation platform to decrease the cost of test and risk and increase the test efficiency of tank experiment and practical test in the sea. On the hardwareintheloop simulation platform, a load model is built to describe the sea environment, and the reliability of simulation system is increased. At the end of the paper, an example shows the validity of the system.
