翼滑艇推进系统模糊控制的仿真比较研究

Comparison between Simulations of Fuzzy Controlling in Gliding-hydrofoil Craft Propulsion System

在Matlab平台上,设计了基于模糊逻辑工具箱的模糊控制器和规则自动拟合模糊控制器;建立了翼滑艇的智能推进系统模型,并用Matlab/Simulink编制了仿真模型;进行了实时仿真。仿真结果表明:规则自动拟合模糊控制器,无论是从超调量方面还是从稳定性方面,都比工具箱的模糊控制器的控制效果好。

On Matlab platform, this paper designs a fuzzy logic controller based on fuzzy logic toolbox and a controller of fuzzy logic rules based on Look-Up Table (2-D). It establishes a model of intelligent propulsion system for gliding-hydrofoil craft. Then, a simulation model is established based on Matlab/Simulink, and real-time simulation is performed. The simulation results indicate that the effect of the controller based on the Look-Up Table (2-D) is better than that of the controller based on Matlab's fuzzy logic toolbox, in both excessive adjusting amount and stability.
