Improved Deadbeat Control Strategy for Linear Induction Machine

Abstract

The deadbeat control (DBC) can track current reference closely, depending on the model of a linear induction machine (LIM). However, the DBC has to consider both the voltage and current constraints for staying in the safe working region of LIM, when calculating the input voltage vector of LIM. To solve such a challenge, one improved DBC with an iterative algorithm is proposed in this paper to solve the voltage and current constraints problem in the traditional DBC. Finally, the improved DBC is applied to 3 kW arc induction motors to verify its effectiveness.
