【摘要】 通过对常规PID控制的分析,结合模糊理论、串级控制理论和专家经验,提出了动态自动整定PID控制系统中3个参数,使系统达到最佳工作状态的方法,从而使系统供水温度恒定。最终试验结果表明,将模糊自整定PID控制系统应用于集中供热时,即使室外温度发生变化,系统也可迅速作出反应,将输出温度稳定在用户所需的舒适度范围内,并且具有较强的抗干扰能力。更多还原

【Abstract】 Through the analysis of conventional PID control,combined with the fuzzy theory,cascade control theory and experience of experts,the three parameters’ method of a dynamic auto-tuning PID control system was put forward which allowed the system to achieve the best working state of the methods to the system water temperature constant. The system final test results showed that when the fuzzy self-tuning PID control system was used in central heating even the outdoor temperature changed,it also could respond quickly to temperature-stable output required for comfort in the user context,and had strong anti-jamming capability.更多还原
