“…Due to the advantages of fast and parallel computation ability, programmable hard-wired feature, low power consumption, shorter design cycle, embedding processor, and higher density, FPGA is better than DSP and becomes the most popular IC in the implementation of the complex computation of the digital estimator or controller system. 18,19 Therefore, in this article, based on the FPGA technology, a realization of a hybrid sensorless controller using I-f startup and EKF is applied in PMSM drive, and it is shown in Figure 1. The FOC, EKF, PI speed controller, SVPWM, and coordinate transformations described by VHDL code are implemented in digital hardware of FPGA.…”

This article presents a hybrid sensorless speed controller for permanent magnet synchronous motor drives using field programmable gate array technology. The If 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 If 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 If 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.
