Greedy Rational Approximation for Frequency-Domain Model Reduction of Parametric LTI Systems
Filip BÄlÃk, Yanlai Chen, Akil Narayan
We investigate model reduction of parametric linear time-invariant (LTI) dynamical systems. When posed in the frequency domain, this problem can be formulated as seeking a low-orde…
