“…It can be seen from the above formula that the LADRC design of the d-q axis is the same, the difference is the amount of disturbance and the selection of bx,y, so the q-axis current loop is taken as an example to design LDARC [15], then:…”

This paper focuses on the vector control scheme of surface-mounted permanent magnet synchronous motorized spindle, to solve the problem of poor speed regulation performance of spindle under high-speed operation conditions, according to the principle of double closed-loop vector control, the characteristics of speed loop and current loop are analyzed, and fuzzy theory is introduced to optimize the traditional speed loop PI controller, furthermore the system parameters are adjusted in real time. Aiming at improving the dynamic response ability of the control system, a first-order linear active disturbance rejection controller is proposed to replace the traditional current loop PI controller, which enhances the anti-interference ability of the system. Experimental results show that the fuzzy PI-LADRC combined control strategy can effectively reduce stator current ripple and torque ripple, and improve the dynamic response speed and anti-interference ability of the system. At last can also improve the output performance of the motorized spindle.

“…LADRC greatly simplifies the problem of parameter setting, which makes ADRC technology more and more widely used in various fields. In Liu et al (2020), a measurement delay compensated LADRC is proposed to eliminate the interference caused by measurement delay in permanent magnet synchronous motor (PMSM) drivers. The LADRC is applied to the motor drive system in Liu et al (2009) to estimate the effect of induction coupling.…”

This paper proposes a linear active disturbance rejection control (LADRC) scheme for a quadrotor unmanned aerial vehicle (UAV) with external disturbances based on adaptive control to address the attitude control problem. Firstly, the dynamic model of the quadrotor is established, and LADRC is used to control the altitude, yaw angle, pitch angle and roll angle of the quadrotor UAV affected by external disturbances, which enhances the anti-disturbance ability of the system. In addition, adaptive control is introduced to solve the problem of difficult parameter tuning in LADRC. Then, the stability of the system is demonstrated by Lyapunov theory. Finally, the simulation results verify the effectiveness of the proposed control scheme under external disturbances.

“…In [39], LADRC was used for disturbance control of a permanent magnet synchronous generator to improve the tracking accuracy of the servo system. In [40], an LADRC method for measuring delay compensation of permanent magnet synchronous motor (PMSM) current loop was proposed; this method improves the disturbance suppression performance under the dead-time effect. In [41], a control strategy based on fractional order ESO was proposed for a PMSM position servo system; this strategy improves the motion accuracy and disturbance rejection ability.…”

Extended State Observer-Based IMC-PID Tracking Control of PMLSM Servo Systems

et al. 2021

Servo systems driven by a permanent magnet linear synchronous motor (PMLSM) are often affected by uncertain disturbances, such as magnetic resistance, friction, and external disturbances, which increase tracking errors and reduce motion accuracy. Traditional control methods may have difficulty to achieve satisfactory control performance in terms of tracking accuracy and disturbance rejection. In this paper, we propose an internal model control PID method based on a model linear extended state observer, which is termed as IMC-PID-MLESO method. With this method, the nominal model parameters of the PMLSM servo system are obtained via system identification. The model linear extended state observer (MLESO), with known parameter information, is designed to improve the estimation accuracy for the system states and total unknown uncertainties. As the uncertainties are compensated in the feedback control law, the PMLSM servo system model is transformed into a known nominal model. Based on the nominal model, the IMC-PID feedback controller is designed to ensure satisfactory performance on disturbance rejection and tracking error reduction. Simulation and experimental results show that the IMC-PID-MLESO method can effectively improve the position tracking accuracy of the PMLSM servo system and rapidly suppress the system disturbance.INDEX TERMS Disturbance suppression, internal model control, permanent magnet linear synchronous motor, tracking accuracy, uncertainties.
