Matlab Models for Multi-Effect Distillation Columns
(paper presented at SIMS 2001
-----------------------------------------------------------------

Sigurd,
Her er Matlab filene mine. Filene for de dynamiske simuleringene ligger
i zip fila Dynamic_simulations.zip og optimaliseringsfilene i
Self_optimizing.zip

Følgende er 'summary' av filene:


The following models are available for simulation with a multi-effect
distillation column:


Dynamic simulation 
run_multiefffect        a program that integrates the derivatives from
multieffect.m, and plots the column profiles and responses 
multieffect     a program that calls and connects the two column models
colamod1.m and colamod2.m and returns the derivatives xprime 
colamod1                the dynamic model for the HP column 
colamod2                the dynamic model for the LP column


Optimisation 
run_optimisation        runs the program optimisation.m, finds the
optimum for the nominal (d0) operating point and the two disturbances d1
and d2 
optimisation    the program with the optimisation routine fmincon  it
calls the programs cola_lv_fun.m and cola_lv_nonlcon.m 
cola_lv_fun             the objective function, calls colamod1 and
colamod2 
cola_lv_nonlcon         the equality and inequality constraints, calls
colmod1 and colamod2 
colamod1                the dynamic model for the HP column 
colamod2                the dynamic model for the LP column


Calculate Loss 
run_loss        calculates the loss L for the disturbances d0, d1 and d2
for each of the controlled variables, calls the program optimisation.m 
optimisation    the program with the optimisation routine fmincon  it
calls the programs cola_lv_fun.m and cola_lv_nonlcon.m 
cola_lv_fun             the objective function, calls colamod1 and
colamod2 
cola_lv_nonlcon         the equality and inequality constraints, calls
colmod1 and colamod2 
colamod1                the dynamic model for the HP column 
colamod2                the dynamic model for the LP column


Vary Heatload 
vary_heatload           program for varying heatload to HP column 
secant_cont     calls multieffect_heatload and finds solution to f(x)= 0
while varying heatload, VB 
multieffect_heatload    calls colamod1 and colamod2 
colamod1                the dynamic model for the HP column 
colamod2                the dynamic model for the LP colum
