Application of the Causal Ordering Graph to Synchronous Motors, Part II: Control Design

摘要

In Part I, the Causal Ordering Graph is applied on rotary and linear permanent magnet synchronous motors. Models are defined in stationary and synchronous reference frame. In this paper, we present the inversion principle of the COG. Then, different control strategies are deduced from established models. Control strategies are developed in Concordia's reference frame (α-β) and Park's reference frame (d-q). Next, principles of controller design are laid out for each selected control strategy. After that, several propositions are made about estimator and anticipation structure. Finally, experimental results validating the effectiveness of our purpose on a linear synchronous motor are presented.
