Abstract
Two practical time-optional controllers for rapid slewing of type-3 an d type-2 third-order plants, PTOS3 and PTOS3tau, respectively, were pr eviously proposed. In this paper, we present results showing that the PTOS3tau is more robust than the corresponding time-optimal controller to both plant parameter variations and flexible unmodeled dynamics. I n addition, a useful numerical method to calculate the time-optimal co ntrols for general linear systems is presented. The results for the PT OS3 and the time-optimal controller for type-3 third-order plants are similar and thus are not detailed.
