Level control (tank 1) of coupled tank liquid level system using integral control state feedback controller

This paper presents the design and modeling for coupled tank Liquid level system using Integral Control State Feedback Controller (ICSF). The ICSF have found wide acceptance and applications in the industries for the past few decades. ICSF controllers are proven to be sufficient for many practical control problems. The modeling for couple tank system, CTS-001 will be done before the designing controller begins. These coupled tank liquid level systems are in second order system. The ICSF Controller will be designed to control the liquid level at tank 1 and design techniques of the ICSF Controller is derived by using pole placement method that are conducted based on developed model. SIMULINK/MATLAB has been used to simulate and verified the mathematical model of the controller. Visual Basic 6 has been used to implement the graphic user interface (GUI) and implementation issues for the controller’s algorithms will also be discussed. The DAQ card has been used to interfacing between hardware and software. Finally, the simulated result will be compared with the implemented result.
