Controlling the temperature of a tank filled with water using Simulink 1.0

We would like to rise water temperature with a heater. Oulet temperature must be equal to the set point temperature (80dlT-C). Proportional-Integral-Derivative (PID) control is used. Inlet water temperature is equal to 20dlT-C. Water flow is equal to 10 m3/hr. Tank volume is equal to 100 m3. Water density and heat capacity are 1 Kg/m3 and 4.19 KJ/(Kg dlT-C). The heater and the temperature measurement device have a first order delay with a time constant equal to respectively 1 and 2. Initial heat input and tank temperature are equal to 2500 KJ/hr and 0dlT-C. This problem is solved using Berkeley-Madonna in Chemical Engineering Dynamics by J. Ingham et al. (second edition, Wiley-VCH, 2000). The solution using Simulink is presented in this page. Sensor temperature lags slightly behind tank temperature. PID control gives best control with no offset and quickly damped oscillations. P, PI and PID control could be tested by simple changes of the PID block parameters.
