Notes ===== To do ----- Notes about files ^^^^^^^^^^^^^^^^^ The FiniteVoume11bck is a newer version of the FiniteVoume11. The new version has a different initialization, and creates a file called startparam.mat. IDZFunDist is used by the file model comparison. (f) Notes about SV ^^^^^^^^^^^^^^ To fix ~~~~~~ How to determine the simulation length for hte initialisation??? Initialisation what happens when UseInitialisation is zero? Describe the ini file Check also for the files for Jeroen the system size issues, so that it works for one size. Group the functions to a separate folder. Make clear about all files what they do. Only the file b_channeltype11 uses the FiniteVoume11 file, all the others are using the bck file. The differences should be analyzed. Note that the finitevoume11 file, before I start messing up it today, was modified 05/24/2017. While the back was modified 07/03/2017 %UseInitialization - it is zero if we ininitalize % - it is 1 when we use an initialization % - it is 2 when we create one, it is an initialisation % run % - if it is 3, we load a file with initial values that we % created when it was less than 3 0: an initialisation based on steady state profile is calculated 1: use given time series for initialisation 2: an initialisation based on steady state profile is calculated, H downstream 3: loading created parameters if UseInitialization==2 DischargeDownstreamBoundary=0; else DischargeDownstreamBoundary=1; end if UseInitialization<3 if UseInitialization==1 H=HinitGiven; HinitH=HinitGiven; else (0 or 2) H=HinitH; end else load startparam HinitH=1; end if UseInitialization<3 save startparam Qt Ksi Hf Q Uf H Af ch end First, establish the equivalence between the two files. The bck with zero should be the same as the 11 without bck. Compatiblity If anywhere you find a Voume11 wihtout bck, it is the same, if bck has the two last parameters zero. Take into account that the new has by default 1 prof factor. Quotation from Litrico's book ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The backwater area A\ :sub:`d` gives the magnitude of the frequency respose of hte sytem for low frequencies, and the time delay :math:`\tau_{d}` is essential to idnetify the limits of performance of hte system, i.e. the maximum achievalbe frequency :math:`\omega_{c}` where perturbations can be rejected. This freqency can be estimated by :math:`\omega_{c} \approx \frac{1}{\tau_{d}}` (Aström 2000; Litrico and Fromion 2001). This is hte best achievable real-time performnace of the contolled system; it is not possible to reject perturbations of freqency higher than :math:`\omega_{c}` with distand downstream feedback control. This is a structural limitation, because it applies for any linear controller. Backwater todo ^^^^^^^^^^^^^^ - Check if the areas are linearly related and if not try to figure out... or leave it. But. - make the program faster by setting the right frequecny. One would not be enough??? - compare it to inertial - Make the file f_ModelComparisonArticle ok. Include the simple bw in it. Make more examples - Check and finalize the ID area and the IDZ parameter calculation functions - idz distributed - analyze the bode plots of trapezoidal and rectangular - test the approximations on trapezoidal and rectangular - Describe alpha, kappa, gamma - Document getting Bode information for the middle and test - Make a separate backwater area calculation, and call it from all the functions - write nicely the backwater area computation - make the two examples to show what it can and what it cannot, use also SV computation - if you have a lot of time: compare SV chezy and manning with the step. Does the final value depend on those? - try to make thus the SV manning. - after having all the files, it would be nice if you could make a complete comparison using csv input - write IR clearly down, implement the shift General todo ^^^^^^^^^^^^^^ - finish the model function documentation - Try to make the old simhydro files run - Especially make a simhydro folder - get back the ability for Sobek scripting Joris paper todo ^^^^^^^^^^^^^^^^ - Make a study and understanding about upstream bodes - Make a connection between categories and normal flow - Revise linear inertial - Based on this, review Hayami, also how distributed they are - Based on this, review id, also how distributed they are - Based on this, review idr, also how distributed they are - code the IR found shift - check linear inertial model - make ir distributed, document it For backwater article --------------------- Article content ^^^^^^^^^^^^^^^ Goal: distributed backwater approximations Show three step responds and its reproducibility We are going to show / test different methods: - based on IDZ - based on Bode - nothing - compared to linear inertial model Make comparisons in time and space domain, using different examples Show results with fricitonless flat canal How to approach the middle of the reach? Dealing with IDZ ^^^^^^^^^^^^^^^^ .. image:: images/BetaGamma.png How to make the idz distributed? """""""""""""""""""""""""""""""" * For the delay it is clear. * For the backwater area I found a method that should be tested. * For the zeros? To do Joris paper ----------------- - order and check the files - make closed loop runs (Python or Matlab?) - make the bode plots - again! - Explain a ctr talk about peak height with bode plots, talking about the sampling time - Make a test with PID as well (start from typical tuning rules) - Write / search for my MPC algorithm 1. Use the categories of Joris, add IR 2. Use the cat. of Joris, make freq. plot 3. Think on Inertial how to do it 4. Put the closed loop - RTC tools??? 5. Look for how to make the Bode plot analytically 6. Create bode from time Publication plans ----------------- Publication bw area, reference Pau, reference Fatiha To read ^^^^^^^ Yolanda Bolea, Vicenç Puig, and Antoni Grau.
