Design of Level Control in A 10 L Pure Capacitive Tank: Stability Analysis and Dynamic Simulation (original) (raw)
2016, International Journal of Science and Engineering
The open loop experiment of a 10 L pure capacitive tank has been successfully done in laboratory. The square tank connected with a pump was designed for investigation in laboratory, and the water was chosen as a fluid with its input volumetric rate of f i (t) [cm 3 /min]. The output volumetric rate of f o (t) can be adjusted by changing the pump voltage of v pu (t) [volt]. The open loop experiment has given the steady state parameters, and it could then be used for calculating the dynamic parameters. This study has proposed the level control configuration of a 10 L pure capacitive tank system; liquid level in the tank h(t) was kept constant by manipulating the pump voltage of v pu (t); and the input water volumetric rate of f i (t) was considered as a disturbance. The P-only-control was implemented to control the level. Purposes of this study are to analyze the stability of the closed loop responses and to do the closed loop dynamic simulation. The closed loop mathematical model was...
