Indirect model predictive control strategy with active damping implementation for a direct matrix converter operating at fixed switching frequency (2017)
Presentation / Conference Contribution
Rivera, M., Dan, H., Tarisciotti, L., & Wheeler, P. Indirect model predictive control strategy with active damping implementation for a direct matrix converter operating at fixed switching frequency. Presented at 2017 CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)

One of the main drawbacks of the implementation of predictive control in a direct matrix converter is the high com¬putational cost and the adequate selection of weighting factors in order to control both input and output sides. In this paper is propo... Read More about Indirect model predictive control strategy with active damping implementation for a direct matrix converter operating at fixed switching frequency.

The design of a position-based repetitive control for speed ripple reduction in PMLSMs (2017)
Presentation / Conference Contribution
Tang, M., Formentini, A., Odhano, S., & Zanchetta, P. (2017, October). The design of a position-based repetitive control for speed ripple reduction in PMLSMs. Presented at IECON 2017 43rd Annual Conference of the IEEE Industrial Electronics Society, Beijing, China

Periodic speed errors can occur in permanent magnet linear synchronous machines for two reasons: 1) a periodic reference signal; 2) cogging force and friction. For reducing such periodic errors, iterative learning control or repetitive control approa... Read More about The design of a position-based repetitive control for speed ripple reduction in PMLSMs.
