Finite Set Model Predictive Control with Imposed Target Dynamic

Abstract:
The so called Finite Set Model Predictive Control (FS-MPC) is well suited to power electronics and electric drives, since it inherently includes the discrete nature of power switches in the optimization. In this paper a new scheme of FS-MPC with Imposed Target Dynamic is investigated for control of a Permanent Magnet Synchronous Motor (PMSM). Inserting the target dynamic simplifies cost function design and gives a insight into relationship between control performance and cost function parameters. Reducing switching frequency at the same time improving the torque and flux quality are two indicators which will be considered in this paper for comparison of the proposed method with classical FS-MPC. Practical implementation on an FPGA-based experimental setup is investigated and measurement results are represented.
