The document discusses various temperature control mechanisms, focusing on the effectiveness of different control algorithms including on/off, proportional, integral, and derivative controllers. It summarizes the advantages and responses of these controllers in managing outlet temperatures of process fluids. Experimental work and dynamic simulations were conducted to compare these control methods, highlighting their performance under changing conditions.

14. Response of On/Off Controller On Changing Set Points

28.  On/Off Controller
On-off controller is the simplest controller and it has some important
advantages. It is economical, simple to design and it does not require any
parameter tuning.
 Proportional Controller
The proportional controller reduces the rise time, increases the
overshoot, and reduces the steady-state error.
 Proportional + Derivative Controller
The proportional + derivative controller reduces both the overshoot
and the settling time.
 Proportional + Integral Controller
PI controller decreases the rise time, increases both the overshoot and
the settling time, and eliminates the steady-state error.
 Proportional + Integral+ Derivative Controller
PID controller is used when dealing with higher order capacitive
processes (processes with more than one energy storage) when their dynamic is
not similar to the dynamics of an integrator (like in many thermal processes).
