Abstract: The sensorless control of PMSM based on control algorithm is a research hotspot in the field ofmotor control. A PMSM sensorless control system based on low-speed pulse and high-frequency stator flux injectionwas proposed，and the traditional stator flux estimator was improved and the high-frequency signal wa...更多

Abstract: Aiming at the problems of chattering and poor observation accuracy of traditional full order slidingmode observer (FSMO), a sensorless control strategy of interior permanent magnet synchronous motor (IPMSM)based on improved full order sliding mode observer was proposed. In this strategy, the quasi-sign func...更多

Abstract: For interior permanent magnet synchronous motor(IPMSM) , accuracy of its discrete-time model isusually at the cost of complexity. To find out a way out of the dilemma, stator flux is chosen as the state variable,allowing its model be represented in the complex form and resulting in a concise model in appear...更多
