“…The PI parameters are designed according to the method in [11]. The speed loop PI parameters are k sp = 0.0368 and k si = 0.92, and the current-loop PI parameters are k cp = 0.6 and k ci = 1080.…”

“…Many effective methods have been proposed in the literature to suppress the adverse impact of these non-ideal factors on the control performance of PMSMs [8][9][10][11][12][13]. In [8], an adaptive linear neuron-based dead time compensation method is proposed for vectorcontrolled PMSM drives, but with a low response at low speeds and without a design standard for learning rate.…”

“…However, this method may fail when the current controller is saturated. In references [11][12][13], parallel resonant controllers and PI controllers are used to suppress the periodic speed fluctuations in the PMSM caused by the current measurement errors, dead zone effect, load disturbance, and other factors, but the multi-resonant controllers increase the computational burden. Reference [14] discusses the negative effect of current measurement errors from the perspective of flux linkage estimation and uses the current loop output results to construct error observers.…”

“…The essential reason why current measurement error causes steady-state speed ripples in PMSMs is that the q-axis steady-state current is not a constant. It includes the harmonic components related to the electrical angular frequency, which can be seen as a periodic disturbance in the forward channel of the speed loop [11]. Other non-ideal factors such as the cogging torque, dead time effect, and flux harmonics also bring about periodic torque disturbances.…”

Repetitive control (RC) has been widely used in many fields due to its excellent ability to suppress periodic disturbances. However, when the permanent magnet synchronous motor (PMSM) operates at variable speeds, the speed loop sampling frequency is usually not equal to an integer multiple of the fundamental frequency of speed ripple, which prevents disturbances from being completely suppressed. In addition, the open-loop gain of the motor control system with RC is too large at certain frequencies, resulting in excessive speed overshoot during startup and loading. To solve these two problems, this paper proposes a fractional order repetitive control (FORC) strategy with dynamically adjustable gain. A fractional order delay link is introduced to make up for the shortcomings of the conventional repetitive controller (CRC) in its ability to suppress periodic speed ripples when the sampling frequency is not an integer multiple of the fundamental frequency of the motor. Then, to weaken the speed overshoot caused by RC, a nonlinear function fal(e,α,δ) is added in the front of the FORC to dynamically adjust the FORC gain. Simulation and experimental results verify the effectiveness of the proposed method.

“…Sources of current measurement errors can be categorized as follows. (1) Gain error is caused by the unequal proportional gain of the current sensors, operational amplifiers, and the passive components in conditioning circuits, which may change with time and temperature [ 16 , 17 , 18 ]. The presence of gain error will generate the torque ripple, leading to the mechanical vibration and decreasing service life [ 19 , 20 ].…”

Field Oriented Control (FOC) effectively realizes independent control of flux linkage and torque, and is widely used in application of Permanent Magnet Synchronous Motor (PMSM). However, it is necessary to detect the phase current information of the motor to realize the current closed-loop control. The phase current detection method based on a sampling resistor will cause a measurement error due to the influence of parasitic parameters of the sampling resistor, which will lead to the decrease in PMSM control performance. This paper reveals the formation mechanism of the current sampling error caused by parasitic inductance and capacitance of the sampling resistor, and further confirms that the above error will lead to the fluctuation of the electromagnetic torque output by simulation. Moreover, we propose an approach for online observation and compensation of the current sampling error based on PI-type observer to suppresses the torque pulsation of PMSM. The phase current sampling error is estimated by the proportional and integral (PI) observer, and the deviation value of current sampling is obtained by low-pass filter (LPF). The above deviation value is further injected into the phase current close-loop for error compensation. The PI observer continues to work to keep the current sampling error close to zero. The simulation platform of Matlab/Simulink (Version: R2021b) is established to verify the effectiveness of online error observation and compensation. Further experiments also prove that the proposed method can effectively improve the torque fluctuation of the PMSM and enhance its control accuracy performance of rotation speed.

To improve the torque control accuracy of an open‐winding permanent magnet synchronous motor with common DC bus, this paper studies a complex vector proportional–integral (CVPI) controller with the help of a proportional–integral (PI) controller to solve the problem of torque ripple caused by the current harmonics caused by the back electromotive force of the motor and the nonlinearity of the inverter. The controller has a higher gain at the center frequency and can realize the tracking of the alternating current (AC) quantity without static error. Therefore, it is used for the tracking control of current harmonics. According to the different characteristics of the dq0‐axis, complex j is realized by orthogonal characteristics and all‐pass filter in the dq‐axis and 0‐axis, respectively. At the same time, with the help of Ansys, Simplorer, and Matlab/Simulink tools, the co‐simulation platform for an open‐winding motor is established, and the motor parameters are optimized. The simulation and experimental results show that the control strategy based on CVPI has stronger harmonic suppression ability, smaller torque ripple, and better dynamic performance than proportional‐resonance (PR) control.
