摘要
提出了一种基于伪降阶磁链观测器的自适应速度辨识方法。根据Popov超稳定性理论得到反馈增益矩阵,克服了基于传统极点配置方法的观测器的不稳定问题,从低速到高速范围,电机都能稳定运行。仿真和试验结果证明了该方法的可行性。
An adaptive pseudoreduced-order flux observer for speed sensorless field-oriented control was presented. The feedback gain matrix was obtained through the Popov, and the unstable question which is based on the traditional pole assignment method was overcome. The motor can run stably from low speed to high speed. The experiments verify that the proposed method is feasible.
