Abstract :
In this paper we describe a worst-case ℋ∞ identification method for multi-input multi-output (MIMO) continuous or discrete-time systems. The method identifies systems from noisy samples of the frequency response. We identify a low-order model and give an upper bound on the error between identified model and true system. Hankel approximation identifies the order and pole positions while Chebycheff approximation improves the optimality of the identified model by tuning the numerator coefficients
