摘要：

针对传统技术采用PLC等通用控制器已无法满足现代化自动控制智能系统要求的问题,文中利用高速、实时性好且内置CAN 控制器接口的DSP,采用变论域PID控制算法,设计基于DSP/F28335的船舶用自动化控制智能辅助系统控制器。文中搭建系统结构并介绍变论域PID算法,并在系统的实时混合仿真平台上进行了相关的干扰实验,用以对比基于传统PID控制器系统的控制效果。实验结果表明,使用变论域模糊PID控制算法的DSP控制器,可较大幅度提高船舶用自动智能控制辅助系统的实时性、抗干扰性和自适应性。

Abstract:

In view of the problem that traditional technology can not meet the requirement of modern 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 structure is established and the variable universe PID algorithm is introduced. The perturbation experiments are carried 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-adaptability of the marine automatic intelligent control auxiliary system.

Key words: marine engine room, automatic intelligent control, digital signal processor, CAN bus, variable universe PID
