新型横向磁通永磁电机无位置传感器磁链自适应直接转矩控制
Direct Torque and Adaptive Flux Sensorless Control of Novel Transverse Flux Permanent Magnet Motors
摘要
Abstract
A novel transverse flux permanent magnet motor (TFPMM) was taken as the control object in this paper.When the novel TFPMM operates in open loop,relatively large torque ripple is inevitable.However,direct torque control (DTC) can be employed to reduce torque ripple.The formation mechanisms of the petaloid stator flux-linkage trajectory in brushless DC drive was analyzed firstly.And then direct torque and adaptive flux sensorless control was proposed as a solution to the problem of stator flux reference existing in conventional DTC.In this approach,the desired voltage vector is only determined by stator flux position and torque hysteresis comparator.And to obtain higher torque per ampere and lower torque ripple,the proposed approach should be cooperated with reasonable angle compensation for the difference of optimal phase advance angle and the angle between stator and rotor flux.The effectiveness and feasibility of the proposed approach are verified through both simulated and experimental results.关键词
