IEEE ACCESS 2023年 11卷 9403-9414页

In this paper, a digitally controlled boost DC-DC power converter featuring a high-resolution Dyadic Digital Pulse Width Modulator (DDPWM) is proposed to achieve Limit-Cycle oscillations (Lcos)-free operation, high DC accuracy, low output voltage ripple at high switching frequency. The effectiveness of the DDPWM in suppressing the onset of Lcos, increasing DC accuracy, and reducing output ripple is verified by both simulink/modelsim co-simulations and experimental testing on a 7-10V input, 13.8V output boost converter operated at 1.17MHz switching frequency. Thanks to the proposed modulator, improvement of more than 6X DC accuracy is achieved compared to a plain digital PWM. Moreover, approximately 3X less output ripple in comparison to a digital PWM with thermometric dithering is achieved.

PMSM (Permanent Magnetic Synchronous Motor) has been increasingly used in many high performance application due to its advantages of high power density, high power factor and efficiency. The design and implementation of a fuzzy-control based speed control IC for PMSM from simulink/modelsim co-simulation to FPGA (Field Programmable Gate Array) realization is presented in this paper. Firstly, a SVPWM scheme, vector control method and fuzzy controller are derived and applied in the speed control IC of PMSM drive. Secondly, the Very-High-Speed IC Hardware Description Language (VHDL) is adopted to describe the behavior of the aforementioned control algorithms. To evaluate the effectiveness and correctness of the proposed speed control IC, a co-simulation work performed by Matlab/simulink and modelsim is firstly conducted. Then, an experimental system by FPGA chip, Nios processor and motor driving board is set up to further validate the performance of the proposed speed control IC. Finally, the results in simulation and in experiment will be compared and discussed. (C) 2011 Published by Elsevier Ltd. Selection and/or peer-review under responsibility of [name organizer]

This article presents a hybrid sensorless speed controller for permanent magnet synchronous motor drives using field programmable gate array technology. The I-f startup strategy is applied to permanent magnet synchronous motor drives at the startup condition and then it will smoothly switch to extended Kalman filter-based sensorless field-oriented control at the adequate condition. The I-f startup is a simple strategy and suitable for the low-speed sensorless control without initial rotor position estimation and machine parameters estimation. Meanwhile, the extended Kalman filter-based sensorless field-oriented control is appropriate for the medium- and high-speed sensorless control. Therefore, combining two approaches, the sensorless permanent magnet synchronous motor can be smoothly operated from a standstill to a high-speed condition. In this article, first, the mathematical modeling of permanent magnet synchronous motor is introduced. Also, the I-f startup strategy is conducted, and the rotor position estimation algorithm by extended Kalman filter is derived. Second, a very high-speed integrated circuit hardware description language is presented to describe the behavior of the adopted estimation and control algorithm. This application codes have been confirmed using simulink and modelsim co-simulation. Finally, a field programmable gate array-based experimental system is utilized to verify the correctness and effectiveness of the proposed hybrid sensorless speed controller for a permanent magnet synchronous motor and a ceiling fan motor.

In this study, we propose a digital hardware implementation of a speed controller for a sensorless permanent magnet synchronous motor (PMSM) drive. First, the extended Kalman filter (EKF) is used to estimate the rotor flux angle (FA) and rotor speed. The estimated rotor FA is sent back to the current loop for vector control and the estimated rotor speed is fed back into the speed loop for closed-loop speed control. A PI controller is utilized in the speed loop control process. Second, we propose the architecture of a simple microprocessor based on the register transfer level method and we design machine code for the PI controller based on the proposed simple microprocessor. Third, the current vector controller and the EKF algorithm are implemented in dedicated hardware and the finite state machine method is used to design the computational process. Fourth, the Very high speed IC Hardware Description Language (VHDL) is employed to describe the behaviors of the simple microprocessor, the current vector controller, and the EKF algorithm. Finally, a co-simulation study was performed using simulink and modelsim to evaluate the effectiveness and correctness of the proposed system, and we present some simulated cases.

This work realizes the speed control for permanent magnet synchronous motor (PMSM) drives under the condition of without position sensor. Rotor flux angle and rotor speed are obtained by using the algorithm of sliding mode observer. And the fuzzy controller is adopted for controlling the speed of PMSM in order to increase the robust performance. In this paper, we provide an approach from modeling, system design, co-simulation in modelsim/simulink to experiment in FPGA which can be used to design and validate our proposed control system. Finally, both simulation and experiment results are confirmed the effectiveness and correctness of the proposed FPGA-based fuzzy speed controller for PMSM which is without position sensor.
