Hi! I am Carlos Olalla, Serra Hunter Professor in the GAEI group of the Dept. of Electrical, Electronic and Automatic Control Engineering in Universitat Rovira i Virgili , Tarragona, Catalonia. I have held the Marie Sklodowska-Curie and also the Beatriu de Pinós individual fellowships in this department, besides of being selected (but not appointed) in the Ramon y Cajal and Juan de la Cierva programs.

Previously, I was a postdoctoral researcher and a lecturer in the Dept. of Electrical, Computer, and Energy Engineering at the University of Colorado at Boulder, USA and also in the MAC group at LAAS-CNRS in Toulouse, France.

My research interests are in the areas of automatic control, power electronics and optimization. Specifically, on new power conversion architectures and control strategies for renewable energy systems (e.g., photovoltaics), electric power distribution, lighting, or wireless power transfer, among others.

I obtained my PhD degree in Advanced Automatic Control and Robotics from the Universitat Politècnica de Catalunya, Barcelona, Catalonia.

Research Profile

Research Profile

My research is focused on the modeling, control, and optimization of power electronics converters and architectures for many applications, such as renewable energy, lighting, or battery management and charging, to name some.

Projects and Research Activities

  • I am currently carrying out research for the ActivRENergy project, funded by the People Programme (Marie Curie Actions) of the European Union's Seventh Framework Programme (FP7/2007-2013) (REA grant agreement #626117), in collaboration with Prof. D. Maksimovic :
    • Distributed power electronics converters for photovoltaic systems increasing the performance and the efficiency of PV installations.
    • Modeling and simulation of PV systems at cell-level.
    • Design of high-energy density power converters for PV systems.
  • I am also interested on the robust control of power converters. Much of my research on this topic has been carried out in collaboration with Prof. I. Queinnec.
    • Analysis and synthesis of controllers for power converters.
    • Development of robust linear controllers and gain-scheduled controllers.
    • Modeling of Nonlinearities, state-dependence, saturation, discretization effects.

PVSims

  • PVSims is a MATLAB toolbox for cell-level simulation of PV systems with distributed power electronics.
  • It is intended to investigate the effects of partial shading and other sources of mismatch, and the efficiency of the different power electronics architectures for its mitigation.
  • This toolbox is one of the results of the ActivRENergy project, which was funded by the EU's People Programme under grant agreement #626117.

Matlab Tricks

This is a compilation of my own notes or documents I found ...

-. Disable warnings (7/03/2017)
Warnings can be disabled by calling 'warning('off', 'WarningId')'.
In order to find out the Id of the last warning you just noticed, use 'warning('query','last')'
-. Dynamic code (29/06/2007)
Sometimes you want to create a code which is very repetitive but you want some changes like indexes or similar, and it can not be done with a 'for' loop.
Note that this is not recommended code practice. See Alternatives to the EVAL() function
This is a very simple example:

for j=1:10
    index=total/j;
    code = [code,'for i=1:',sprintf('%d',index),10];      %10 is the code for new line
    code = [code,'value(i)=',int2str(plant(j)),10];        %sprintf or int2str are used to convert the numbers to strings
    code = [code,'end',10];
end
eval(code);


-. Escape a quotation (29/06/2007) Originally taken from this link

>> eval('disp(''''''This is a string'''''')')
'This is a string'


-. Escape a single quote (29/06/2007)
To escape a single quote in a string (which could be used for 'eval')

Use '' (two simple quotes) to replace the original '
Example:
code_plant=[code_plant,'[P',sprintf('%d',i),',r]=sconnect,(''iload;r'',''Int;G([1])'',''Kt:Int;G([2])'',''G:iload;Kt'',plant(:,:,i),''Int:e=r-G([1])'',sint);',10];


LaTeX Tricks

This is a compilation of my own notes or documents I found ...

-. Unnumbered equations (10/08/2007)

\begin{equation*}
\end{equation*}


B)-. Split equations (10/09/2008)

Usually the best choice to split equations is the 'split' environment. Avoid 'array' whenever possible.
\begin{equation}
\label{whatever}
\begin{split}
x = & a + b + c + d + \\[optional vertical space]
& e + f + g + h.
\end{split}
\end{equation}
