چکیده
The traditional sensorless control system of permanent magnet synchronous motor (PMSM) has the problems low estimation accuracy and poor anti-interference ability. Moreover, position performance is subjected to harmonic ripples caused by inverter nonlinearities flux spatial harmonics. To optimize dynamic PMSM system, this paper proposes a scheme that combines integral backstepping with enhanced linear extended state observer (ELESO). ELESO consists two observers (LESOs), which estimate internal external disturbances improve rotor position. Then, controller processes estimated speed information obtain d q-axis voltages. implemented in Matlab/Simulink verified experiments. simulation experiment show can effectively suppress load interference accuracy.

On Position Sensorless Control for Permanent Magnet Synchronous Motor Based on a New Sliding Mode Observer
For the problems of buffeting and phase delay in traditional rotor detection in sensorless vector control of permanent magnet synchronous motor (PMSM), the Sigmoid function is proposed to replace sign function and the approach of piecewise linearization is proposed to compensate phase delay. To the problem that the output of traditional low pass filter contains high-order harmonic, two-stage fi...
متن کاملSimple Sensorless Control of Interior Permanent Magnet Synchronous Motor Using PLL Based on Extended EMF
This paper proposes an improved sensorless control to estimate the rotor position of an interior permanent magnet synchronous motor. A phase-locked loop (PLL) is used to obtain the phase angle of the grid. The rotor position can be estimated using a PLL based on extended electromotive force (EEMF) because the EEMF contains information about the rotor position. The proposed method can reduce the...
متن کاملMRAS Based Sensorless Control of Permanent Magnet Synchronous Motor
Speed and torque controls of permanent magnet synchronous motors are usually attained by the application of position and speed sensors. However, speed and position sensors require the additional mounting space, reduce the reliability in harsh environments and increase the cost of a motor. Therefore, many studies have been performed for the elimination of speed and position sensors. This paper i...
