The components of a heater control system are shown in Fig. 11.24. The time constants of the actuator, process and transducer are 5, 20, and 100 s. The improvement of the performance of the ACS is proposed introducing a supplementary sheath of the resistor which doubles its time constant, allowing a larger controller gain.

Draw the diagram of the ACS response to a reference temperature change of 10 % in both cases.
