中文摘要
      提出了动态递归模糊神经网络(DRFNN)以在线估计电液位置跟踪系统中包括非线性、参数不确定性、负载干扰等在内的未知动态非线性函数,基于lyapunov稳定性理论推导出DRFNN可调参数和估计误差的界的自适应律,并构造出稳定的自适应控制器.实验结果表明:基于DRFNN的自适应控制器可使电液位置跟踪系统具有较强的鲁棒性和满意的跟踪性能.
英文摘要
      Dynamic recurrent fuzzy neural network(DRFNN) is proposed to evaluate online the unknown dynamic nonlinear functions that include nonlinearity,parameter uncertainty,load disturbance et al.in electro-hydraulic position tracking system,adaptive laws of the adjustable parameters and the evaluation error bounds of DRFNN are formulated based on Lyapunov stability theory,and a stable adaptive controller is synthesized.The experimental results show that the adaptive controller based on DRFNN can make electro-hydraulic position tracking system more robust and obtain satisfactory tracking performance.
