Abstract :
An alternative method for gain scheduling is considered, based on so called affine linear parameter varying systems (LPV) and an ℋ ∞-like method. It is shown that the necessary constraints for existence of such a controller can be reduced. This decreases the computational burden, in the process of finding a controller. The method is illustrated by application to a 3-state Moore-Greitzer compressor model. The nonlinear model is rewritten as a so called quasi-LPV system which the control synthesis is based on, and the derived controller is simulated with the nonlinear model
