Hippe P. Windup in Control. Its Effects and Their Prevention

Springer, 2006. — xviii, 314 p. — (Advances in Industrial Control). — ISBN 978-1-84628-322-2.The problem of windup prevention in the presence of stable plants has been a well-researched field for a long time. The solutions presented, however, are based on various interpretations of the windup effects and, consequently, the remedies offered also look quite dissimilar at first sight. At a closer inspection, however, the various approaches can be represented in a unified scheme, with certain parameters adapted to the special approach.
The prevention of windup in the presence of unstable systems has not yet reached the same state of maturity. As the prevention of controller windup is not influenced by the location of the plant poles, the difficult problem to solve in open loop unstable systems is the prevention of plant windup. There are numerous papers on constrained control for unstable systems, but most results only apply to special problems and/or require mathematical tools not commonly used by engineers.
This book presents solutions to the prevention of windup for stable and unstable, single input and single output (SISO), as well as multiple input and multiple output (MIMO) systemsUndesired Effects of Input Saturation.
