Abstract :
A novel approach for the design of robust controllers for discrete-time uncertain systems using a multiplier approach is given. Our algorithm is based on a mu-synthesis type iteration involving a search for a suitable multiplier and solving a scaled H∞ optimization problem. The design is performed entirely in the discrete-time domain. The computational efficiency of the algorithm is due to the usage of direct discrete dynamic scalings obtained without bilinear transformation and curve fitting
