船舶用自动控制智能辅助系统设计.

In view of the problem that traditional technology can not meet the requirement of modem automatic control intelligent system with general controllers such as PLC, This study designs an intelligent auxiliary system controller for marine automatic control based on DSP/F28335 by using DSP with high speed, good real - Time performance and built - in CAN controller interface and variable universe PID control algorithm. The system strncture is eitabtisked and the variable universe PID algorithm is introduced. The pe1turbation experiments rule caffied out on the real - time hybrid simulation platform of the system, and the control effect based on the traditional PID controller system is compared. Experiments show that the DSP controller using variable universe fuzzy PID control algorithm greatly improves the real - Time, anti - interference and self - adaplability of the mruine automatic intelligent control auxitiru-y system.
