Finite-Control-Set Model Predictive Torque Control With a Deadbeat Solution for PMSM Drives
TL;DR: This paper proposes a control strategy of finite-control-set model predictive torque control with a deadbeat (DB) solution for permanent-magnet synchronous motor drives that relieves the big calculation effort of the traditional FCS-MPTC method.
Journal ArticleDOI
Dynamic Loss Minimization of Finite Control Set-Model Predictive Torque Control for Electric Drive System
TL;DR: In this article, a dynamic optimization strategy of finite control set-model predictive torque control for permanent magnet synchronous machines is proposed, which takes into account the inverter losses and machine losses simultaneously.
Journal ArticleDOI
High-Frequency Injection-Based Stator Flux Linkage and Torque Estimation for DB-DTFC Implementation on IPMSMs Considering Cross-Saturation Effects
Wei Xu,Robert D. Lorenz +1 more
TL;DR: In this paper, a new method for high-frequency injection (HFI)-based self-and mutual incremental inductance estimation is proposed and evaluated in both simulations and experiments, where the estimated incremental inductances including cross-coupling inductance due to cross saturation are curve fitted offline and then used to calculate the apparent inductances.
Journal ArticleDOI
Dynamic Loss Minimization Using Improved Deadbeat-Direct Torque and Flux Control for Interior Permanent-Magnet Synchronous Machines
Wei Xu,Robert D. Lorenz +1 more
TL;DR: In this paper, the instantaneous dynamic loss model, which is a function of volt-second selection in each switching period, containing nonlinear effects such as minor hysteresis loops is theoretically derived and evaluated by both FEA simulation and experiments.
Journal ArticleDOI
Reduced Parameter Sensitivity Stator Flux Linkage Observer in Deadbeat-Direct Torque and Flux Control for IPMSMs
Wei Xu,Robert D. Lorenz +1 more
TL;DR: In this paper, a flux observer that utilizes disturbance input decoupling (DID) is proposed to estimate the stator flux and torque in a DTC system, where the flux estimation error due to the parameter variations is decoupled through the disturbance information from a stator current observer.
