Direct Torque Control of Permanent Magnet Synchronous Motor With Reduced Torque Ripple and Commutation Frequency
Yongchang Zhang,Jianguo Zhu +1 more
TL;DR: A very simple but effective method to obtain the duty ratio of the active vector by appropriately arranging the sequence of the vectors is proposed, and the commutation frequency is reduced effectively without performance degradation.
Journal ArticleDOI
Model Predictive Current Control for PMSM Drives With Parameter Robustness Improvement
TL;DR: Simulation and experimental results both show that the proposed method can effectively eliminate the influence of the parameter mismatches on the control performance and reduce the parameter sensitivity of the MPCC method.
Journal ArticleDOI
Two-Vector-Based Model Predictive Torque Control Without Weighting Factors for Induction Motor Drives
Yongchang Zhang,Haitao Yang +1 more
TL;DR: In this article, the authors proposed an improved model predictive torque control (MPTC) without the use of weighting factor, where the torque and flux magnitude references are converted into an equivalent reference vector of stator flux, hence eliminating the weighting factors of stators flux in conventional MPTC.
Journal ArticleDOI
Model Predictive Torque Control of Induction Motor Drives With Optimal Duty Cycle Control
Yongchang Zhang,Haitao Yang +1 more
TL;DR: An improved MPTC with duty cycle control is proposed by optimizing the vector selection and its duration simultaneously when minimizing both torque and flux errors, and better steady-state performance at both low and high speeds is achieved, even if the sampling frequency is reduced by half.
Journal ArticleDOI
Model Predictive Direct Power Control of a PWM Rectifier With Duty Cycle Optimization
TL;DR: In this article, the authors proposed an improved model predictive direct power control (MPDPC) for a PWM rectifier by using a duty cycle control, which achieves good steadystate performance and quick dynamic response by selecting the best voltage vector, which minimizes the errors between the reference power and the real power.
