A Sampling Theorem for Exact Identification of Continuous-time Nonlinear Dynamical Systems
Zhexuan Zeng, Zuogong Yue, Alexandre Mauroy +2
Low sampling frequency challenges the exact identification of the continuous-time (CT) dynamical system from sampled data, even when its model is identifiable. The necessary and su…
