Fixed-Switching Frequency Finite-State Model Predictive Thrust and Primary Flux Linkage Control for LIM

Received: 14 February 2023;  Published: 09 May 2023;  doi: 10.21926/jept.2302017

Abstract

The special design of linear induction machines (LIMs) leads to adverse effects caused by the longitudinal and end effects. These effects make the thrust control of the LIMs most attractive because its value decreases sharply with the speed increase. Thus, finite-state model predictive control (FS-MPC) is developed to increase the performance of the LIMs. However, the variable switching frequency is the main drawback of this control. Consequently, the main objectives of this paper are to propose FS-MPC with a const [...]
