Switching Frequency Limitation With Finite Control Set Model Predictive Control via Slack Variables
Year: 2025
Type: article
Abstract: Past work proposed an extension to finite control set model predictive control to simultaneously track both a current reference and a switching frequency reference. Such an objective can jeopardize the current tracking performance, and this can potentially be alleviated by instead limiting the switching frequency. To this end, we propose to limit the switching frequency in finite control set model predictive control. The switching frequency is captured with an infinite impulse response filter and bounded by an inequality constraint; its corresponding slack variable is penalized in the cost function. To solve the problem efficiently, a sphere decoder with a computational speed-up is presented.
