The present work is an attempt to put together the most
relevant aspects of the engineering problems involving distributed
parameter systems (D.P.S.'s). Simulation and optimal
control are explained in detail in Chapters II and III.
The original contribution of this thesis is given in
Chapters V and VI, where modal control theory and a gradient
subroutine that searches for the optimal reference coefficients
are used. As a result, it was possible to obtain an
output distribution better than the one achievable by the
known methods. This technique works in situations of strongly
nonlinear control and compensates the effect of having the
analyzer and synthesizer approximated by low order matrices.
It also makes it possible to give higher weight to some zones
of the output distribution in order to have a better local
fit. The necessary background for understanding Chapters V
and VI is given in Chapter IV.
