The Open Loop Parameters

Table 9.2: Open loop parameters

Initial Heater Reading	Final Heater Reading	Average Temperature($^0$C)	$K_p$	$\tau _p$
10	15	31.57	0.41	53.37
20	25	36.00	0.50	52.64
30	35	41.79	0.58	49.21

It can be seen from the graphs that there is a lag of approximately 6 seconds in each experiment.
