Patent number: 11984826Abstract: Reduced computation time for model predictive control (MPC) of a five level dual T-type drive considering the DC link capacitor balancing, the common-mode voltage (CMV) along with torque control of an open-ends induction motor based on determining a reduced set of switching states for the MPC. The reduced set of switching states are determined by considering either CMV reduction (CMVR) or CMV elimination (CMVE). Cost function minimization generates a voltage vector, which is used to produce gating signals for the converter switches. The reduced switching state MPC significantly reduces computation time and improves MPC performance.Type: GrantFiled: November 2, 2022Date of Patent: May 14, 2024Assignees: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALS, King Abdullah City for Atomic & Rewnewable Energy (K.A.

Patent number: 11870373Abstract: Capacitor balancing of a dual three-level (3L) T-type converter based on silicon carbide (SiC) discrete semiconductors was performed with the converter feeding an open-ends induction motor (OEIM). A model predictive control (MPC) using a two step cost function calculation was developed to balance the DC link capacitors and control the machine torque simultaneously. The number of redundant switching states used was reduced without affecting the operating voltage vectors, which substantially reduced the computational time. A simulation and experimental results are in good agreement.Type: GrantFiled: March 10, 2020Date of Patent: January 9, 2024Assignee: King Fahd University of Petroleum and MineralsInventors: Aboubakr Salem, Mohamed Ali Abido, Mohamed Mamdouh

Patent number: 11119457Abstract: A method for controlling an electric drive system and the electric drive system. The method includes: measuring an external variable; estimating a control variable for a current sampling step with a mathematical model; predicting a control variable for a future sampling step for each of a plurality of candidate voltage vectors selected for the future sampling step; and calculating a cost function, and identifying a primary voltage vector giving a minimum, where the cost function is defined as a deviation between the predicted stator flux and the reference stator flux. The method further includes: predefining a lookup table giving a correlation between a nonzero voltage vector and a voltage vector group including four candidate voltage vectors, where the plurality of candidate voltage vectors is selected referring the lookup table. The electric drive system includes motor, power converter, and controller, and configured to perform the method.Type: GrantFiled: June 26, 2019Date of Patent: September 14, 2021Assignee: King Fahd University of Petroleum and MineralsInventors: Mohamed Mamdouh El Shormbably, Mohamed Ali Abido
