The Smith prediction compensation algorithm can not be used for unstable dead﹣time processes control directly.In order to make the compensation control of Smith predictor be stable in closed﹣loop sys﹣tem,a dynamic general controller was applied to the integrative﹣plus﹣dead﹣time model.This method takes full use of the feedback control of velocity and acceleration,which improved control quality of the system. Moreover,the meaning and determining method of instability correction factor Kp was given.The simula﹣tion results show that this method has good robustness,few adjustable parameters and simple configura﹣tion,which is convenience to the actual application.%Smith 预估补偿算法不能直接用于不稳定大滞后系统的控制。对此，基于一种动力学通用控制器，使得积分加纯滞后对象(IPDT 模型)的 Smith 预估补偿控制闭环稳定。该方法充分利用了通用控制器的系统运动速度和加速度负反馈作用，提高了系统的控制品质。同时，给出了不稳定系统校正系数 Kp 的含义及确定方法。仿真对比表明，该控制方法具有较好的鲁棒性，可调参数少，调整简单，易于组态，便于实际应用。
