Anti-windup, bumpless transfer and reliable designs: a model based approach

In this paper, the L/sub 2/ anti-windup approach introduced by A. R. Teel et al. (1997) is applied to the problem of bumpless transfer in (saturated) multi-controller systems, and to the problem of designing highly reliable saturated control systems exploiting hardware redundancy. We illustrate the L/sub 2/ anti-windup technique by means of a simple physical example and illustrate its application to the above mentioned problems using this example and an example taken from the literature.
