摘　　要：针对温控医用灌注泵的应用过程对温度控制的要求及其所具有的时滞性、非线性、模型结构不确定等特点,我们结合模糊控制技术和常规PID控制方法,组成模糊自整定PID控制器。将传统PID和自整定模糊PID控制器分别应用于温控医用灌注泵系统。实验结果表明,模糊自整定PID控制器在动态性能、稳定时间和稳态误差方面均比传统PID的效果好。We designed a self-tuning fuzzy PID controller,which combined the theory of fuzzy control with conventional PID con-troller.Then the conventional PID controller and the self-tuning fuzzy PID controller were respectively applied to the thermostatic medical infusion pump.The result shows that the self-tuning fuzzy PID controller has better dynamic performance,shorter setting time and smaller steady-state error than the conventional PID controller.
