【摘要】 为了提高对大惯性大时滞复杂受控对象的控制品质,采用基于I-Fuzzy-Smith算法的融合控制策略方法,研究了受控对象的控制难点,集成模糊、Smith预估和积分控制优势,给出了I-Fuzzy-Smith融合控制算法,构建了三种控制结构的仿真模型。结果表明:该策略是合理可行与有效的,其算法控制精度高,系统动、静态控制效果好,表现出很强的鲁棒性,I-Fuzzy-Smith控制算法的动、静态控制品质和鲁棒性优于另外两种算法。更多还原

【Abstract】 To enhance the control quality for complex controlled object with large time lag,the authors invetigated the control puzzle of controlled object. Based on the fusion based control strategy of I-Fuzzy-Smith algorithm and the integration of the advantages of PID and Smith estimator,the study provides an I-Fuzzy-Smith control algorithm and builds a simulation model with three kind of control structures. The simulation results demonstartes that it is sound and feasible,high in control precision,better in dynamical and steady control effect,and very robustness.更多还原
