Scientific degrees:
PhD, Technical University of Sofia, 2004, thesis “Numerical methods for
Analysis and Synthesis of Robust Control Systems”
Summary of
the Thesis work:
The main goal was
to develop new, fast and numericaly reliable software
for design of robust control algorithms in state-space. The numerical
properties of the algorithms for H∞ design and µ synthesis
were investigated and the factors affecting the accuracy of the results were
explored.
As a result, new
package for robust control systems design was drawn up. It consists of both
FORTRAN 77/95 solvers and MATLAB interface (mex)
files. It is now included in the free (open source) library SLICOT, developed
by the leading European specialists in Control Theory under the EU project
NICONET (http://www.icm.tu-bs.de/NICONET).
My contribution to
the library are several programs for H∞ design via different
methods, a program for µ synthesis via DK iterations and a bunch of supporting
programs, along with an interface to MATLAB, which allows these solvers to be
directly invoked in its user friendly environment. The control algorithms
synthesized this way are suitable for both continuous and discrete systems in
presence of parametric uncertainty and can be directly implemented in all
modern PLCs and control computers.
Working positions:
·
Institute for Nuclear Research and Nuclear Energy – Sofia, Research
Engineer (2003 - 2005).
The main goal of
my work there was to develop and apply a software for simulation of positron
annihilation in metal crystals for the purpose of the non-destructive defectoscopy of nuclear reactors’ bodies. I took
participation in the development of a set of programs in FORTRAN 77, MATLAB and
C++ for modeling of metal crystal structures and
electron layers via solving quantum mechanics equations, simulation of positron
annihilation in the crystal and the lifetime of the positron in the crystal,
which is used for evaluation of the number and type of crystal defects. A
number of numerical tests were made and the results compared with real
experimental data.

Technical
University of Sofia, Assistant Professor (2005 -)
My teaching
activities at present include the following courses:
- Practical Optimization. The aim of the
course is to make the students acquainted with the classical methods for optimization,
as well with the modern methods in optimization in Control Theory like genetic
algorithms, linear matrix inequalities and others.
- Robust and Optimal Control. The students
are introduced to the identification, modelling, analysing and synthesis of
control algorithms (especially µ-synthesis) for complex systems with parametric
and non-structured uncertainties in the model.
- Control Theory – an Introduction.
Along with the
teaching activities, my main scientific interests continue to be in the field
of robust control algorithms design and developing MATLAB software. In
accordance with my work I also took participation in an exchange program in
Germany to get acquainted with Simatic series PLCs by
Siemens.
·
As a part time
job, I took participation in the development of low-cost automation systems. I
was involved in the development of the following products:
- stand-alone programmator for PIC16
processors (system software in assembler)
- system for remote control of electric consumption for home users
via public GSM network (system software in assembler)
- small PLC (system software in assembler)
- program for spectra processing, in collaboration with
Institute of Electronics – Sofia (software in MATLAB)
- set of units for
ultrasound, magnetometric and thermoelectric defectoscopy of metallic materials (including the computer
interface to the unit and analyzing program in
MATLAB), in collaboration with Institute of Mechanics - Sofia.
