Abstract

This chapter explains how the model recovery anti-windup (MRAW) structure can be applied to other problems. For plants with both input rate and magnitude saturation, the scheme can be employed to recover the performance of a controller synthesized for the system without input magnitude and rate saturation. From a mathematical viewpoint, input rate saturation can be modeled by augmenting the plant equations. The chapter first considers how the MRAW scheme can be generalized when dealing with magnitude- and rate-saturated inputs before discussing the MRAW solution to the windup problem in the case of dead-time plants. It also describes bumpless authority transfer in multicontroller schemes and reliable control via hardware redundancy.
