Abstract

This paper presents a comparative investigation of four predictive torque control (PTC) strategies for two-level three-phase inverter fed induction motor drives. Among the considered PTC strategies, three novel PTC schemes based on bus-clamping techniques are developed. The proposed bus-clamping PTC (BC-PTC) schemes are founded on the basis of the clamping of each stator phase during 60°-interval in every half-cycle of the stator quantities. The performance of the four considered PTC strategies are evaluated through several simulation results at steady-state operation, with emphasis on various comparison criteria, such as: stator phase voltage and current waveforms, stator flux ripple, electromagnetic torque ripple, average total harmonic distortion, average switching frequency, average switching loss factor, and average quality factor. The simulation results reveal that the proposed BC-PTC schemes are much more efficient in terms of torque ripple, switching frequency, and switching power losses over the entire range of the stator frequency.

IM驱动器母线箝位PTC策略的比较研究

本文对两电平三相变频馈电异步电动机驱动的四种预测转矩控制策略进行了比较研究。在考虑的PTC策略中，提出了三种基于母线箝位技术的PTC方案。本文提出的母线箝位PTC (BC-PTC)方案是基于定子数量每半周期60°间隔内每个定子相位的箝位。通过稳态运行时的多个仿真结果对四种PTC策略的性能进行了评价，重点考虑了各种比较标准，如定子相电压和电流波形、定子磁链纹波、电磁转矩纹波、平均总谐波畸变、平均开关频率、平均开关损耗因数和平均品质因数。仿真结果表明，在整个定子频率范围内，BC-PTC方案在转矩纹波、开关频率和开关功率损耗方面具有更高的效率。
