摘要
本文将纯滞后环节进行一阶Taylor逼近后,根据内模控制原理,得到了单位反馈PID控制器的参数整定值,然后运用仿人智能的方法得到被控对象的静态增益,由此来自动调整控制器的比例系数。仿真结果表明,增益自适应内模PID控制器能克服增益变化对控制性能的影响,显著改善控制品质。
By approximating time delay link using Tayler series, the PID parameters can be got based on the internal model control (IMC). And then the static gain of controlled object is obtained by artificial intelligence method. Using this method, the proportional factor of IMC-PID controller can be regulated. Simulation shows that the gain adaptive IMC can overcome the influence resulted from the gain variation of system.
