摘　　要：提出了一种大纯滞后系统新预估控制方法,对大纯滞后系统进行了有效的模糊控制。该控制方法与纯滞后时间τ无关,方法简单,易于工程实现,使常规模糊控制在大纯滞后系统的控制中如同对无纯滞后系统的控制一样有效。文中证明了该方法使系统的稳定性与系统的纯滞后无关,并经MATLAB仿真验证,该法具有良好的控制品质,且能适应对象参数和结构有一定变化的时滞系统。This paper presents a new predictive control method for time-delay systems with long pure time delay , which effectively solved the control problem of them with fuzzy control. It has nothing to do with the ＂r-pure time delay , which is simple and should be realized easily in engineering , but have a general fuzzy-controller control time-delay systems with long pure time delay as control no time-delay systems. The paper proved that the new predictive control method makes the control systems stability have nothing to do with the ＇r - pure time delay , but it is proved with the simulation of MTALAB and possesses a good control quality and can be suitable to systems with parameters and structure-varying within a limit .
