Modern micro analytical systems used for polymerase chain reaction (PCR) require fast, damped tracking response. The control of the temperature of the PCR reactor can be represented as shown. The controller is chosen to be PID controller, denoted by Gc(s), with a prefilter, denoted by Gp(s). The transfer function is [30]

It is required that the percent overshoot P.O.
