Abstract: |
The
paper presents simulation experiments on the con- tinuous
stirred tank reactor for hydrolysis of propylene oxide to propylene glycol.
The reactor is exothermic one. There are two parameters with only
approximately known values in the reactor. These parameters are the reaction
rate constant and the reaction enthalpy. The simplified mathematical model of
the reactor consists of four nonlinear ordinary differential equations. The
steady state analysis shows the reactor has multiple steady states and the
open-loop analysis confirms that the reactor is open-loop
unstable around one of these steady states. Then the possibility to stabilize
the reactor using static output feedback PI and PID controllers is studied.
Because of the presence of uncertainty in the continuous stirred tank
reactor, the robust static output feedback is designed. Simulations are used
for testing the stabilizability of the reactor
around its open-loop unstable steady state. |
