Abstract :
In this paper transient management techniques are investigated in a scenario where the reconfiguration or replacement of a forward-loop controller is required due to changes in the environment or in the plant. Such a change in the closed control loop may have undesirable transient effects, which may degrade the performance of the controlled system. Since the transient cancellation and reduction schemes used in open-loop systems can not be used here, new solutions are proposed for run-time transient handling
