High-performance control, precise torque regulation, and minimal stator current total harmonic distortion (THD) of induction motor drives (IMDs) have always been considered an industrial concern. The conventional finite control set model predictive control (FCS-MPC) strategy suffers from high computational complication, increased torque ripple, and stator current THD, which is employed to drive the voltage source inverter (VSI) based IMD. This paper proposes an optimized method of selecting prediction vectors to minimize the computational cost of the traditional FCS-MPC for a two-level VSI-bas...

We have squandered 80 years on a wrong conception of how our economy works. There is much to fix…

Abstract This paper presents a continuous control set model predictive control (MPC) based advanced switching sequence (SS) for the single-phase three-level grid connected neutral point clamp converters. The SSs are developed considering the tracking performance of the current feed to the utility grid, balancing the dc-bus capacitors voltages as well as the switching loss in the semiconductor devices. In the proposed strategy, the number of pole state change (SC) per control cycle is only 2, while in the conventional optimum switching sequence and the multiple voltage vector (VV) based MPC (p...

As part of a personal push to learn more about non-linear control, I have been playing around with a pretty powerful method known as trajectory optimization. Once the base code is set up, it’s fairly easy to go apply to various systems. Here’s a fun example of it being run on a drone: Drone performing flips! While waiting for Starship SN15 to launch (it was in fact scrubbed, sad), I decided to pull together an estimate for some of it’s dynamics and see if I could get my toy 2D simulation to perform that epic flip and land itself. To my excitement, after some finessing, it worked quite w...
