摘　　要：针对一些工业控制对象中出现的纯时滞、大惯性、时变不确定性等问题 ,提出了基于模糊逻辑来智能调整PID控制器参数的方法 ,并且将其应用到了一类药剂温度控制系统当中 .另外 ,还给出了此方法的硬件和软件实现 .最后 ,实际系统的运行结果表明此方法能够降低被控量超调、提高控制精度并且增强系统的鲁棒性 ,证明其在一类过程对象的应用中优于传统的PID控制方法 .Aiming at such problems as time delays, large inertia, uncertainties in some industrial control plants, an intelligent tuning method of PID controller with fuzzy logic which was used in a temperature control system of medicament was presented. Moreover, a realization of this method in hardware and software was also provided. Finally, the practical results after system running show that the controller can reduce large overshoot, increase control accuracy and make system effective in robustness to model uncertainties,meanwhile prove the superiority of this intelligent tuning method of PID controller over the classic one in the application of a kind of process plants.
