Power electronics systems are physical devices that can be modelled
mathematically as controlled dynamical systems. This makes them suitable
for the application of existing control theory, particularly in the
design of their regulatory subsystems. For years there has been a
perceived need to bring the disciplines of power electronics and
theoretical control into closer co-operation, demonstrating the
potentially great advantages of, at first sight, rather obscure control
theory to power specialists while making control technicians better
aware of the fundamental needs and limitations of power electronics
design.
Control Design Techniques in Power Electronics Devices deals
specifically with control theories relevant to the design of control
units for switched power electronics devices, for the most part
represented by DC-DC converters and supplies, by rectifiers of different
kinds and by inverters with varying topologies. The theoretical methods
for designing controllers in linear and nonlinear systems are
accompanied by multiple case studies and examples showing their
application in the emerging field of power electronics. The book is
introduced through the very important topic of modeling switched power
electronics as controlled dynamical systems. Detailed circuit layouts,
schematics and actual closed-loop control responses from a
representative group of the plants under discussion and generated by
applying the theory are included.
The control theories which feature in the book are: sliding mode control
and feedback control by means of approximate linearization (linear state
feedback, static and dynamic proportional-integral-differential (PID
control), output feedback trough observer design, Lyapunov-based control
and passivity-based control). Nonlinear control design methods
represented include: exact feedback linearization, input-output
linearization, differential flatness, generalized PID control and,
again, passivity-based control.
This monograph will be of interest to researchers in power systems and
their related control problems. It will also assist tutors and students
in these fields with its dydactic style and its rich source of
worked-out application examples from a broad spectrum of control
theories.
