建立了双容水箱系统的数学模型,采用串级控制方案对双容水箱液位系统进行控制,控制算法采用数字PID。确定了硬件设备,制作了双容水箱液位控制系统。采用力控5.0 版组态软件,对整个液位控制系统进行组态,构成控制精度高,显示直观的双容液位系统。 关键词:双容水箱;数学模型;串级控制;组态软件 Abstract: The mathematical model of the double-tank is developed, the cascade control-scheme and digital PID algorithm have been adopted in this system. Made a control system of double-tank by chooses appropriate hardware. The configuration software of ForeControl V5.0 can be used to configuration, structure a double-tank level control system which is high-precision and intuitionistic display.
