| 论述了大延迟系统控制方案的优化方法，针对Smith预估器在干扰信号下的输出分量衰减较慢的问题，提出了在完全抗干扰Smith预估器中引入微分环节，并推导出它的传递函数。通过仿真试验，取得了缩短系统的响应时间，加快了系统对误差响应的控制效果，表明这种控制方案对大延迟系统的控制具有较强的实用价值。 |

| Abstract: |
| The optimization of control scheme for long delay system is discussed. Against the slowattenuation of Smith predictor's output under interference,a differential section is added into Smith predictor. Its transmitting function is derived. The simulative test shows that a better control effect is achieved,which shortens the system response to error. |
