摘　　要：针对常规PID控制器由于参数固定无法实现对水温的精确控制,在常规PID控制的基础上引入模糊控制技术,设计了模糊自适应PID控制器,其控制参数随着控制对象的变化而自动调整;采用离线计算、在线查询模糊控制表,以满足系统实时处理的需要。搭建了基于DVP-28SV系列PLC的模糊自适应PID水加热控制系统实验平台,用WinCC组态监控软件实时监视温度曲线,实验结果表明,设计的水加热系统克服了水温的大时滞性,保证了水温的精确控制,具有较强的稳定性和抗干扰性。According to the fixed parameters conventional PiD controller is unable to realize accurate water temperature control, Fuzzy control technology is introduced based on conventional to design a fuzzy self-adaptive PID controller,which control parameters is able to automatically online regulate in accordance with the changes of the controlled object.The method of off-line inference and on-line look-up fuzzy control table is used to meet the requirement of real-time process.The ex- perimental platform for the water heating system was studied based on the fuzzy self-adaptive PID controller with DVP- 28SV PLC,and real-time monitoring of water temperature is realized by the general configuration software WlNCC.
