Direct Torque Control of Interior Permanent Magnet Synchronous Motors Based on Sliding-mode Active Flux Observers
提出了一种有效磁链滑模定子磁链观测器.与一般滑模磁链观测器不同的是该观测器并不包含转速自适应环节,从而避免了由于转速估计误差所导致的磁链观测性能下降.采用Lyapunov稳定性理论证明了观测器渐近收敛.通过实时估计有效磁链信息,间接计算出电机转速,从而实现内置式永磁同步电机(IPMSM)的无速度传感器直接转矩控制.仿真结果表明了该方法的有效性.
A sliding-mode observer based on"active flux"concept was proposed. Different from the conventional stator flux linkage observer,this observer was not consisted of the speed adaptive loop. Therefore,it was immune to estimate of speed error which would make the performance of the observer worsen. The Lyapunov stability theory was employed to prove that the observer was asymptotically stable. By using the estimated active flux angle,the motor speed could be cal…查看全部>>
