Abstract
The use of Process Reaction Curve (PRC) method for tuning of temperature control parameters in a 10 L stirred tank heater has been studied experimentally. An electric heater was employed as a means to heat the liquid in tank and to maintain its temperature. In order to create a process reaction curve, an open loop experiment was done in laboratory. The electric heat load (qe) was suddenly changed from 420 Watt (initial value) to 500 Watt (new steady state value) at time equals 2 min. As a result, the liquid temperature in tank rises from 31 to 32 °C at time equals 6 min. This open loop temperature response was then used for tuning of PID temperature control parameters; the tuning results are as follows: gain controller Kc=77 Watt/°C, integral time constant I = 300 second, and derivative time constant D = 75 second. Furthermore, closed loop simulation using computer programming was also done to evaluate the resulted tuning parameters. The developed mathematical model of temperature control system in stirred tank heater was solved numerically. Such mathematical model was rigorously examined in Scilab software environment. As shown in closed loop simulation, closed loop responses in PID control were faster than those in P and PI controls.
