摘　　要：针对系统的大滞后和参数不确定性,依据推导出的二阶系统参数变化扰动补偿公式,提出了一种新的Smith预估控制系统的改进方案.即使在未知被控对象数学模型的情况下,该方案也可以很好地解决大滞后系统的控制问题.本文提出的方法结构简单,可调参数少,易于调整和实现.仿真实验证明,该方法具有更好的自适应能力和鲁棒性能.For the dead-time and parameter uncertainties, a new improvement program of Smith prediction control system is presented based on the deduced parameter changes disturbance compensation formula of second-order system. Deadtime system control problem is effectively solved by this proposed method even in case that the mathematical model is unknown. The method includes simple structure and less tuning parameters, and it allows adjustment and realization easily. The simulation results show that this method has better adaptive capacity and robustness.
