| 摘 要： | 针对常规模糊控制系统在控制过程中精度比较低的问题,将模糊控制系统离线得到的模糊控制表与线性插值算法结合起来,提出一种基于线性插值的模糊控制方法,该方法可以在线计算出系统的控制输出,克服控制器因输入输出量化所造成的调节死区以及稳态误差和稳态颤振的缺点,从而达到提高模糊控制系统控制精度的目的。利用Matlab的Simulink工具进行仿真研究,对3条不同类型的船舶仿真试验结果表明,所设计的线性插值模糊控制器与常规的模糊控制器相比,具有良好的控制性能和实用性。 |

| Abstract: | Aimed at the lower accuracy of conventional fuzzy control systems in control processes,a new fuzzy control method based on linear interpolation is presented by combining fuzzy control table obtained in off-line control with linear interpolation algorithm.This method can calculate the control output of system on line,can improve control precision and overcome steady-state flutter.By utilizing Matlab toolbox the simulation studies are carried out.The simulation results for three ships of different types show that the designed controller has higher effectiveness and practicability in comparison with the conventional ship fuzzy controller. |
