【摘要】 集中供热系统二次侧供水温度控制属于大惯性、大迟延系统。随着供热系统热负荷变化,导致用户端供水温度波动明显。为使其温度恒定在55～75℃,采用模糊自整定PID和常规PID串级控制相结合,使构成的模糊PID控制器不仅具有常规PID控制器的特性,而且具有智能控制器的自适应能力,增强系统对不确定因素的适应性。通过模糊自整定PID串级主控制器控制规则的建立和控制器的仿真,验证了模糊自整定PID串级控制方法的可行性。更多还原

【Abstract】 The secondary side water supply temperature control belongs to great inertia and long delay system for central heating.The user-end water temperature changes greatly with the variation of heating load.In order to make the temperature between 55~75 ℃,combined fuzzy self-tuning PID control with conventional PID cascade control,That PID controller did not only have characteristics of conventional PID control,but also possess the characteristic of intelligent control and the self-adaptive ability,and the adaptability of uncertainties for system was enhanced.the feasibility of fuzzy PID self-tuning cascade controller is validated by establishing the control rules and simulation.更多还原
