DYNAMIC SIMULATION AND COMPOSITION CONTROL IN A 10 L MIXING TANK
The open loop experiment of composition dynamic in a 10 L mixing tank has been successfully done in<br />laboratory. A 10 L tank was designed for mixing of water (as a stream-1) and salt solution (as a<br />stream-2 with salt concentration, c2 constant). An electric stirrer was employed...

| description | The open loop experiment of composition dynamic in a 10 L mixing tank has been successfully done in<br />laboratory. A 10 L tank was designed for mixing of water (as a stream-1) and salt solution (as a<br />stream-2 with salt concentration, c2 constant). An electric stirrer was employed to obtain uniform<br />composition in tank. In order to keep the liquid volume constant, the system was designed overflow. In<br />this work, 2 composition control configurations have been proposed; they are Alternative-1 and<br />Alternative-2. For Alternative-1, the volumetric-rate of stream-1 was chosen as a manipulated<br />variable, while the volumetric-rate of stream-2 was chosen as a manipulated variable for Alternative-<br />2. The composition control parameters for both alternatives have been tuned experimentally. The<br />volumetric-rate of manipulated variable was changed based on step function. The outlet stream’s<br />composition response (c3) to a change in the input volumetric-rate has been investigated. This<br />experiment gave Proportional Integral Derivative (PID) control parameters. The gain controllers Kc<br />[cm6/(gr.sec)] for Alternative-1 and Alternative-2 are -34200 and 40459 respectively. Integral time<br />constant ( t<br />I) and Derivative time constant (tD) for both alternatives are the same, i.e. t<br />I = 16 second,<br />and tD = 4 second. Furthermore, closed loop dynamic simulation using computer programming was<br />also done to evaluate the resulted tuning parameters. The developed mathematical model of<br />composition control system in a mixing tank was solved numerically. Such mathematical model was<br />rigorously examined in Scilab software environment. The results showed that closed loop responses in<br />PID control were faster than those in P and PI controls. |
