Predictive Torque Control of a Four-Switch Three Phase Inverter Fed PMSM
摘要
Abstract
To the question that big torque ripple and poor adaptive capacity existed in conventional methods for four-switch three phase inverter fed PMSM system, a optimization strategy of torque ripple based on model predictive control was proposed. When a fault occurs, the structure of inverter was switched and the performance index function was updated. So the torque ripple was restrained significantly and the steady and dynamic performance of system was improved. Meanwhile the midpoint voltage was balanced. The simulation results showed that the proposed method was effective and achievable.关键词
