Model and control for coupled tanks using labview uri icon


  • This paper presents a digital proportionalintegral controller implementation for a Coupled Tanks System for liquid level control. The model identification is done by sinusoidal signal at different frequencies, as result the bode plot obtained is applied for designing the controller. One of the main advantages of programming the digital controller in Labview is the possibility of sending small gains which allow to get a better performance for fixing the parameters: settling time and overshoot. Since the system is nonlinear the mathematical model is also presented to compare with the experimental model obtained. The obtained results on simulation are shown as well as the implementation of two PI controllers one in the control module that has the tanks system used (CE105MV) and another in Labview. © 2013 IEEE.
