A dynamic windup compensation scheme applied to a turbofan engine

We address the problem of performance degradation due to the presence of constraints on the manipulated input for a MIMO turbofan engine. To this end, a nominal H/sub /spl infin// controller designed by Frederick et al. (1996) is augmented with the anti-windup scheme proposed previously by us (1997). In addition, a technique is presented which ensures set-point tracking without offset for key outputs when the overall nominal set-point is not feasible due to input constraints.
