DOI: 10.1109/jas.2020.1003138
Abstract: Stably inverting a dynamic system model is fundamental to subsequent servo designs. Current inversion techniques have provided effective model matching for feedforward controls. However, when the inverse models are to be implemented in feedback systems,… read more here.
