For experiments with same values of We and Wu:
- Not much difference was seen in heater value trends and temperature value trends for all the experiments performed above.
- Reason for this will be clear from the discussion on the trends mentioned below (for experiments with different values of We and Wu)
For experiments with different values of We and Wu:
- Keeping We as large (around 100) and Wu as small (2) shows better performance as compared to the case when the values are kept the other way around.
- With We very small (say around 1-2), oscillations are less, and the settling time observed was found to be more.
- With increase in We, the oscillations were observed to increase and the settling time was found to reduce and hence, better control was observed.
- So, with increase in We, any error is quickly dealt with, because with increase in We, we are actually increasing the significance of change of temperature in deciding the control action.
- With increase in Wu, oscillations reduced and the settling time was found to increase and hence, less preferred.
So, the best performance is obtained for the cases with high We and low Wu.
