纯滞后系统自适应Fuzzy-Dahlin控制的研究

Research on Adaptive Fuzzy-Dahlin Control for System with Time-delay

针对工业控制过程中普遍存在的大惯性、纯滞后、时变性、非线性对象的控制问题,为了在对象参数发生变化时,仍能达到较好的调节效果,提出自适应Fuzzy-Dahlin控制策略。仿真结果表明,该方法对此类控制具有超调小(可达到无超调)、调节时间短、鲁棒性好等优点,可以较好地解决纯滞后系统的控制问题。

A control strateny constituted by adaptive Fuzzy-Dahlin is proposed in order to solve the control difficulty of the plant with bin inertia,pure time-delay,nonlinear,time-change characteristic,when a good control performance is resulted from the change of the system parameters.The simulation results indicated that the Fuzzy-Dahlin makes the extra-regulation more small ,the regulation time more short,and the robustness better for the controlled plant,and control system with time- delay can be solved better.
