UTFPR Chemical Reactors Discussion

2. In a CSTR reactor, a first-order, irreversible, isothermal, liquid-phase reaction occurs, whose species A reacts to form product B. The reaction constant k and the residence time is 2. A group of chemical engineering students from UFSCar planned develop a reactor-specific controller so that to changes in the setpoint, deltaCasp, the concentration of A at the reactor outlet, Ca, responds according to a ramp up to the new setpoint in a time interval deltat (this is the so-called trajectory reference) by manipulating the Cai feed concentration.

What is the transfer function of the developed controller? Is the controller PID type? Does it have full action?
