减摇鳍模糊参数自整定PID控制器设计及仿真研究

以船舶减振鳍控制系统作为对象，应用模糊控制理论，提出一种基于Fuzzy推理的PID参数自整定控制器，完成在线PID控制器参数模糊自整定的理论实现。并且在考虑船舶模型的非线性和不良浪向下，对系统进行了仿真。仿真结果表明，与常规PID控制相比，基于Fuzzy推理的PID参数自整定控制器，具有更好的控制效果和更强的鲁棒性。

Design and Simulation of Fuzzy Parameter Self-adjusting PID Controller of Fin Stabilizer

This paper,taking ship fin stabilizer control system as an object,applying fuzzy control theory,has come up with a PID parameter self-adjusting controller based on fuzzy reasoning,so as to realize the theory of on-line controller parameter fuzzy sel-adjusting.Moreover,the system is simulated with the non-linearity of ship model and different wave directions taken into account.Simulation results show that,compared with conventional PID controller,the PID parameter self-adjusting controller based on fuzzy reasoning is of much better control effects and stronger robustness.
