摘要
用计算机仿真过程控制系统ＰＩＤ调节器的工程整定法，即采用凑试法、衰减曲线法、临界比例度法和响应曲线法等，研究了改变ＰＩＤ调节器的比例（Ｐ）、积分（Ｉ）、微分（Ｄ）参数对系统过渡过程性能的影响，得到了仿真响应曲线。
The methods of PID controller engineering tuning algorithm by using computer simulation in process control system are introduced. It shows that the changes of P、I、D parameters of PID controllereffect on the system interim process performance. The simulation response curves are obtained by the simulating test.
