The process parameters of a temperature controlled system are given as follows: K=19, t-2 min. ve ta = 0.1 min a) Find the PID parameters using the Cohen-Coon and Ziegler-Nichols methods. b) Gy = 1; Gm = 1 Draw the PID control response of the output variable for unit positive and negative step effects on the set point of the process output variable. c) Compare the control performances (ISE and IAE) of the Cohen-Coon and Ziegler- Nichols methods.
