“…where bn and f0n are the estimated value of b n and f 0n . Then, by transforming Equation ( 19) into the frequency-domain, the following transfer functions are obtained: (21) where λ(s) is the characteristic polynomial of LESO, λ(s) = s 3 + β 1n s 2 + β 2n s + β 3n . It should be noted that a lowercase letter is used to represent a time-domain variable, whereas the corresponding capital letter is used to represent the variable in the frequency-domain, e.g., x(t) and X(s).…”

“…In [20], a dual LADRC-based control scheme is proposed, in which the speed LADRC considers the disturbance induced from iron losses, and the current LADRC minimizes the torque ripple by estimating the disturbance corresponding to the back-EMF. In [21], a higher-order LADRC is studied, in which the conventional dual loop structure is replaced by a single loop structure. Thus, the speed can be directly controlled with faster dynamics.…”

This article presents an improved linear active disturbance rejection control (LADRC) method for interior permanent magnet synchronous motor (IPMSM) drives. The proposed method adopts a dual LADRC structure. The outer LADRC-based speed regulator adopts position feedback instead of speed feedback so that the low-pass filter for speed calculation can be eliminated. The inner LADRC-based current regulator incorporates a maximum torque per ampere (MTPA) operation scheme to improve the torque output capacity and the efficiency of the motor. In addition, considering the variation of load inertia in real applications, a systematic modelling and analysis on the effect of inertia mismatch is presented. To enhance the robustness of the drive system to inertia mismatch, an inertia identification method is proposed, in which the inertia information is extracted from the estimated disturbance of speed loop LESO. Finally, the effectiveness of the proposed method is verified on a 1.0-kW IPMSM drive platform.

“…Permanent magnet synchronous motor (PMSM), due to small size, high torque density, excellent efficiency and performance, has been widely used in industrial fields, especially in robotics, aerospace and other occasions and fields, which have high requirements on motor performance and control precision (Boubaker et al , 2019; Guo et al , 2019; Hao et al , 2021; Jayaprakasan et al , 2020; Yan et al , 2018; Yuan et al , 2019). However, the PMSM is subject to the total disturbances including modelling errors, unknown dynamics and external disturbance caused by load mutation in practical engineering systems (Sun et al , 2020; Zuo et al , 2021).…”

Purpose This paper mainly aims to deal with the problems of uncertainties including modelling errors, unknown dynamics and disturbances caused by load mutation in control of permanent magnet synchronous motor (PMSM). Design/methodology/approach This paper proposes an enhanced speed sensorless vector control method based on an active disturbance rejection controller (ADRC) for a PMSM. First, a state space model of the PMSM is obtained for the field orientation control strategy. Second, a sliding mode observer (SMO) based on back electromotive force (EMF) is introduced to replace the encode to estimate the rotor flux position angle and speed. Third, an infinite impulse response (IIR) filter is introduced to eliminate high frequency noise mixed in the output of the sliding mode observer. In addition, a speed control method based on an extended state observer (ESO) is proposed to estimate and compensate for the total disturbances. Finally, an experimental set-up is built to verify the effectiveness and superiority of the proposed ADRC-based control method. Findings The comparative experimental results show that the proposed speed sensorless control method with the IIR filter can achieve excellent robustness and speed tracking performance for PMSM system. Research limitations/implications An enhanced sensorless control method based on active disturbance rejection controller is designed to realize high precision control of the PMSM; the IIR filter is used to attenuate the chattering problem of traditional SMO; this method simplifies the system and saves the total cost due to the speed sensorless technology. Practical implications The use of sensorless can reduce costs and be more beneficial to actual industrial application. Originality/value The proposed enhanced speed sensorless vector control method based on an ADRC with the IIR filter enriches the control method of PMSM. It can ameliorate system robustness and achieve excellent speed tracking performance.

To improve the dynamic quality and control performance of the permanent magnet synchronous motor speed control system, a novel sliding mode control method with improved reaching law for PMSM was proposed, which has a shorter reaching time and small system chattering. An extended state observer (ESO) based on the hyperbolic tangent function for the sliding mode controller is designed to realize the real-time tracking of the mechanical angular velocity and load disturbance of the motor, which can weaken the influence of the internal parameter perturbation and external load disturbance. The performance of the novel sliding mode controller for PMSM was simulated based on MATLAB/Simulink. An experimental platform based on dSPACE is built. The simulation and experimental results show that this novel PMSM controller can effectively suppress the system chattering and improve the dynamic performance and robustness of the system.
