“…We assume that the system is excited by an unknown exogenous input, and we use measurement data for x 1 and v 2 . We then identify the PTF from q 1 to v 2 using a µ-Markov structure RLS algorithm, taking advantage of zero buffering [10]. To verify the identified PTFs, we identify the first 4 Markov parameters and compare these with their corresponding analytical values.…”
