挤塑机温控系统中模糊-PI复合控制的应用

Application of Fuzzy PI Compound Control to Temperature Control System in Plastic Machine

将模糊控制器用于温控系统的控制,克服了传统PID控制参数整定繁琐,对控制对象的参数变化缺乏自适应性的不足,提出了Fuzzy-PI复合控制算法,实验结果表明,采用复合控制的温控系统具有稳态精度高和鲁棒性强的特点。

A fuzzy controller is persented to conquer the temperature control system, which overcomes the over - laborate procedure of the traditional PID control parameter and gives the Fuzzy - PI compound control algorithm in terms of the shortcomings of lacking self- applicabiliy when the parameter of the controlling object changes. The results of experiments show that the application of the compound temperature control system has highly steady accuracy and good robustness.
