“…The permanent magnet synchronous motor (PMSM) is widely used in industry field because it is provided with the advantages of high controllability, high efficiency and high‐power‐factor operation [1]. Field oriented control (FOC) is increasingly applied in the PMSM control system to achieve accurate control of motor speed and position [2]. The exact rotor position information is indispensable for FOC in which the magnitude and phase of armature current must be adjusted according to the rotor position to accomplish instantaneous torque control [3].…”

“…And some researchers adjust the amplitude of the sensor output voltage signals to unit amplitude to minimise the amplitude errors [14]. Low-pass filter is adopted in hardware to filter out high frequency noises and software algorithms are used to correct the amplitude phase deviation of the signal [2]. The notch filter and the adaptive notch filter (ANF) are widely used in electronic control systems [15,16].…”

Accurate position signals are essential for a vector control system. To obtain accurate position signals, high‐precision position sensors such as optical encoder and resolver are employed. However, they are usually restricted by the environmental condition and cost. Linear Hall‐effect sensors, possessing tiny size, light weight and low cost, are usually used to detect position signals. However, the position signals detected by linear Hall‐effect sensors in low cost conditions always contain a large part of high‐order harmonics, which will decrease the validity and reliability of sensor measurement. In this paper, to eliminate the influence of harmonics, a short‐distance harmonic suppression method without any low‐pass filter is proposed. The proposed method utilises three linear Hall‐effect sensors displaced a certain electrical angle to dissolve the position signal. Through simulation analysis and experimental verification, the proposed method has been proven to be effective in suppressing the third‐order and fifth‐order harmonics.

An observer is a crucial part of the sensorless control of a permanent magnet synchronous motor (PMSM). An observer, based on mathematical equations, depends on information regarding several parameters of the controlled motor. If the motor is replaced, then we need to know the motor parameter values and reset the observer’s parameters. This article discusses an intelligent observer that can be used for several motors with different parameters. The proposed intelligent observer was developed using machine learning methods. This observer’s core algorithm is a modified Jordan neural network. It processes Iα, Iβ, vα, and vβ to produce Sin θ and Cos θ values. It is combined with a phase-locked loop function to generate position and speed feedback information. The offline learning process is carried out using data acquired from the simulations of PMSM motors. This study used five PMSMs with different parameters, three as the learning reference sources and two as testing sources. The proposed intelligent observer was successfully used to control motors with different parameters in both simulation and experimental hardware. The average error in position estimated for the simulation was 0.0078 p.u and the error was 0.0100 p.u for the experimental realization.
