Design of Liquid Level Control System Based on Simulink and PLC

Abstract

Double-water tank is simulated by using hardware-in-loop simulation platform in this design. Semi-physical simulation is realized by the computer, SIMULINK and using QuaRC. On this basis, the monitoring operating of double-water tank can be realized by PLC. First the controlled object is analyzed the model to build the physics model on SIMULINK, communicate with PLC by means of data sampling module and monitor the change of liquid level by WinCC configuration software, design and build remote computer process control system, complete control system experiment result analysis.
