4. A process has first-order-plus-time-delay dynamics. That is, the transfer function relating the changes in the output y to changes in the input u is Y'(8) Ke-os U'(s) TS +1 A set of data samples of the step response of the process has been collected as follows: Timet 0.0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 3 4 5 Input 1 1 2 2 2 2 2 2 2 2 2 2 2 Output y 2 2 2 2 2.001 2.363 2.659 2.902 3.101 3.264 3.398 4 2 Based on the above data, estimate the parameters K, 0, T
