The controller can be designed for different operating points simultaneously. The design of the hold function is carried out in two steps: first the closed-loop discrete-time behaviour is determined by choosing a suitable output injection gain; integral action is incorporated to guarantee zero steady-state error. In a second step this discrete-time behaviour is approximately realized by output feedback with generalized hold. Minimization of a quadratic performance index simultaneously for all operating points yields hold functions with good intersample behaviour. A practical design example and experimental results illustrate the proposed method.en0143-2087200127593Generalized hold functionIntegral actionOutput feedbackOutput injectionRobust controlSampled-data controlIngenieurwissenschaftenJournal Article10.1002/oca.684Journal Article
