The PID controller is the most common option in the realm of
control applications and is dominant in the process control
industry. Among the related analytical methods, Internal Model
Control (IMC) has gained remarkable industrial acceptance due to
its robust nature and good set-point responses. However, the
traditional application of IMC results in poor load disturbance
rejection for lag-dominant and integrating plants. This book
presents an IMC-like design method which avoids this common pitfall
and is devised to work well for plants of modest complexity, for
which analytical PID tuning is plausible. For simplicity, the
design only focuses on the closed-loop sensitivity function,
including formulations for the H∞ and H2 norms. Aimed at graduate
students and researchers in control engineering, this book:
Considers both the robustness/performance and the servo/regulation
trade-offs Presents a systematic, optimization-based approach,
ultimately leading to well-motivated, model-based, and analytically
derived tuning rules Shows how to tune PID controllers in a unified
way, encompassing stable, integrating, and unstable processes Finds
in the Weighted Sensitivity Problem the sweet spot of robust,
optimal, and PID control Provides a common analytical framework
that generalizes existing tuning proposals
Extremality results proved in this Monograph for an abstract
operator equation provide the theoretical framework for developing
new methods that allow the treatment of a variety of discontinuous
initial and boundary value problems for both ordinary and partial
differential equations, in explicit and implicit forms. By means of
these extremality results, the authors prove the existence of
extremal solutions between appropriate upper and lower solutions of
first and second order discontinuous implicit and explicit ordinary
and functional differential equations. They then study the
dependence of these extremal solutions on the data. The authors
begin by developing an existence theory for an abstract operator
equation in ordered spaces and offer new tools for dealing with
different kinds of discontinuous implicit and explicit differential
equation problems. They present a unified approach to the existence
of extremal solutions of quasilinear elliptic and parabolic
problems and extend the upper and lower solution method to elliptic
and parabolic inclusion of hemivariation type using variational and
nonvariational methods. Nonlinear Differential Equations in Ordered
Spaces includes research that appears for the first time in book
form and is designed as a source book for pure and applied
mathematicians. Its self-contained presentation along with numerous
worked examples and complete, detailed proofs also make it
accessible to researchers in engineering as well as advanced
students in these fields.
