A nearly interpolatory algorithm for H-infinity identification with mixed time and frequency response data
A new algorithm is proposed for H-infinity identification with mixed-time and frequency-response data. This algorithm shares similar properties to interpolatory algorithms, and is nearly interpolatory. Meanwhile, it greatly reduces the computational complexity of the interpolatory algorithm. Worst-case identification error bounds are also characterized, and derived for this nearly interpolatory algorithm. A numerical example is used to illustrate the proposed identification algorithm.
