摘　　要：为有效进行偏航迎风控制,提高偏航控制系统偏航过程中的稳定性与鲁棒性,提出了一种新型的偏航系统控制方法——Fuzzy-PID合成控制方法。该控制方法将整个速度控制域分成三个部分:大误差范围内的Fuzzy控制部分;小误差范围内的Fuzzy-I控制部分;微误差范围内的Fuzzy-I-PD控制部分。以此方法设计了Fuzzy-PID合成控制器,并构建了偏航矢量控制系统。采用Matlab进行的仿真实验结果表明,与常规PID控制和模糊PID分段控制比较,在系统稳定性和鲁棒性方面,Fuzzy-PID合成控制具有更好的性能表现,增加了系统的安全系数。In order to carry out yawing control effectively, and enhance the stability and robust of yawing control system, the paper proposes a new method for yawing control system named Fuzzy-PID synthesis control. The control method mainly consisted of three parts： the Fuzzy control part of big error scope, the Fuzzy-I control part of small error scope, the Fuzzy-I-PD control part of micro error scope. Fuzzy-PID synthesis controller is designed according to the method, and yawing vector control system is built. Comparing the simulation curves with common PID control and fuzzy PID subsection control, the results indicate that the Fuzzy-PID synthesis control system has better performances in the stability and robust of yawing system, which increases the safety factor of system.
