摘要
利用Matlab软件内置的模糊控制工具箱为液压振动桩锤(SFA1600型,中频液压振动桩锤)主、从动偏心块设计了相位差模糊控制器,对模糊控制器进行了参数自校正优化,建立了参数自校正模糊控制器的Simulink仿真模型。结果表明:参数自校正模糊控制器可以有效地控制主、从动偏心块的相位差,避免因相位差的偏离导致振动不同步的问题。经模糊控制器调节后的上、下偏心块的相位差与给定相位差相比,误差较小。参数自校正模糊控制器与基本模糊控制器相比,响应快、稳态性好、稳态误差小。
Using the fuzzy control toolbox embedded in Matlab, the fuzzy controller for phase difference was de- signed for active eccentric block and driven eccentric block in the hydraulic vibrohammer （ type SFA1600, medium- frequency hydraulic vibrohammer）. The fuzzy controller was optimized with parameter self-adjusting method and the simulation model was developed. The results showed that parameter self-adjusting fuzzy controller regulated phase difference very well to avoid the problem of non-synchronous vibration. The error between the difference and the given phase difference was small. Compared regulated phase with the basic fuzzy controller, parameter self-adjus- ting controller possessed the advantages of fast response, good stability and small steady-state error.
