Blending Experiment: Constant Outflow 1
Experimental Conditions
In this first experiment the diluent and concentrate flows are the same.
Hence the initial conditions will be:
- Flow in of Concentrate = 2.5 units per time
- Flow in of Diluent = 2.5 units per time
- Initial concentration of concentrate in the tank = 0.5 units per volume
- Initial holdup in tank = 10 units
- Initial flow out of tank = 5 units per time
- Valve constant (doesn't alter) = 0.5
Pre-Experimental Questions
This experiment has been split into three sections:
- Obtaining the Gain Matrix
- Obtaining the RGA
- Running With Two Control Loops
The first two parts are a quantitative analysis of the system to obtain
the gain matrix and Relative Gain Array. The third part is simply a
qualitative analysis of the system to verify the findings of the first
two parts.
Please work through each of these in turn answering the questions as you
go along.
Note: You can reset the controller parameters to their default settings at
any time by clicking on the reload/refresh button in the browser toolbar. Unless specified
in the experiment instructions, the defaults should be used.
