摘　　要：自适应交互算法实现简单,能够在未知系统模型的前提下完成控制参数梯度递减,使系统控制性能趋向优化。将自适应交互算法引入到传统的PID控制器中,构成一种自适应交互PID控制器,将该控制器应用到宝钢2050粗轧液压立辊压下系统中,结果表明在外界扰动和系统工况发生变化时,该控制器能够自适应调节控制器参数,使控制系统取得满意的控制效果。Adaptive interaction algorithm, whose advantage is easy to implement, can perform gradient descent of control parameters without any knowledge of plant. Based on adaptive interaction theory and classical PID controlling theory, an adaptive interaction PID controller is developed. The good performance of adaptive interaction PID is verified by the application of hydraulic edger screwdown system in Baosteel 2050 rough mill. The results show that the adaptive interaction PID controller achieves better performance than the classic one, especially, in the circumstance of foreign disturbance and working condition variation.
