“…However, this modeling may not be useful to implement a linearized control law for an accurate estimation of the internal state of the PMBLDCM. Therefore, modeling in the dq-frame can be effectively decoupled as given in (2), considering the effect of iron loss [7], [26], [29].…”

Variable frequency drives (VFDs) have been used for position sensors for many years. Alternatively, reliable VFDs for smart autonomous systems require the simultaneous configuration of sensors and sensorless operation. This paper details the design and implementation of a continuous fast terminal (CFT) sliding mode controller (SMC) based speed controller and speed estimation through the CFT sliding mode observer (SMO) that accounts for iron loss while calculating total disturbances. The rotor speed dynamics of the PM brushless DC motor (PMBLDCM) drive system is first investigated considering lumped disruption (interference, parametric complexity, and non-linear dynamics). The built-in SMC can control the rotor speed in real time, as well as analyze and compensate for aggregated interruptions in rotor speed dynamics. Additionally, the field-oriented control (FOC) method is developed to maximize torque production while drastically minimizing torque ripples. With this approach, the zero torque pulsation constraint is gradually achieved at a wide speed range. The validation of the proposed CFT-SMC with FOC is carried out using simulation and experiments. According to the comparative study, the proposed sensorless control outperforms conventional methods due to the inclusion of iron loss. Index Terms-PM brushless DC motor, continuous fast terminal sliding mode controller, sensorless field-oriented control, torque ripple, voltage source inverter I. INTRODUCTIONLow-powered Electric vehicles and high precision industrial applications benefit from permanent magnet brushless DC motors (PMBLDCM) [1]. In addition to improving the torquespeed characteristics, the application would also increase the torque-weight ratio, improve control sensitivity, and reduce vibration. As a result of magnetic alignment and winding configuration, PMBLDC is characterized by a trapezoidal back electromagnetic force (EMF), which demands a specific control strategy to maintain the electromagnetic torque. Normally, PMBLDCM works in a six-step conduction mode, Manuscript

A PV three-phase grid following inverter (GFI) with LCL filters can reduce current harmonics and deliver active power to the grid. Controlling such higher-order systems is challenging due to system uncertainties, grid voltage variations, and filter resonance. Active disturbance rejection control (ADRC) provides resilience to these uncertainties and a prompt response to disturbances. A linear extended state observer and a phaselocked loop observer are integrated into the ADRC structure to optimize tracking performance. The proposed controller uses a structured inner and outer closed-loop ADRC that takes into account process delays and extended state observer dynamics. The GFI can operate under variable grid voltage frequencies or even deviations in frequency caused by grid failure, and is able to meet these challenges as part of the design process and the synchronization approach. Both simulation and experimental results are given to validate the dual ADRC-based methods for an 8 kW laboratory prototype PV-GFI system.

Improved Linear Active Disturbance Rejection Control for IPMSM Drives Considering Load Inertia Mismatch

et al. 2022

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.
