The design and realization of ship dynamic positioning controller based on DSP

A dynamic positioning controller based on the digital signal processor (DSP) is designed for certain crane vessel on the basis of the SRI-VC2110DP dynamic positioning system developed by Shanghai Ship and Shipping Research Institute. Based on the actual needs for the dynamic positioning controller, the hardware circuit consisting of dual CAN bus interface, dual Ethernet interface and I/O interface centering on the core processor has been developed and hardware equipment has been tested. To test the function and performance of the controller designed and developed, the dynamic positioning application program is developed on the SYS/BIOS real-time operation system and the simulation platform is built to verify the real-time performance and reliability of the controller.
