摘要
提出了一种新型的基于模糊逻辑的PI参数自整定方法.它与别的方法相比,具有结构简单,占内存少,运算速度快的特点,并能较好地兼顾控制系统要求的各项指标.文中还给出了这一方法应用于主汽温串级控制系统的例子,作了计算机仿真实验。理论和实验都表明了该方法的可行性.
The paper presents a new self-tuning method of parameters for PI controller. The method, which is based on fuzzy logic and derived from theories of fuzzy control, has many advantages of simple structure, small storage space, quick calculating speed compared with other available methods. It gives consideration to all performance indexes required by controll system. The application of the method to PI controller of cascade control system for main steam temperature is also presented. Both theoretical analysis and computer simulation have shown the feasibility of the method.
