“…Because of the extra components and signal delays, the sine signals in the sinusoidal pulse-width modulation (SPWM) block and input voltage in the inverters are implemented in the "Voltage Norm" block shown in Fig. 1 [9]- [10]. This method is useful in terms of integrated sensorless chips that generate no delay or signal distortions.…”

This work proposes a highly efficient sensorless motor driver chip for various permanent-magnet synchronous motors (PMSMs) in a wide power range. The motor driver chip is composed of two important parts. The digital part is a sensorless controller consisting mainly of an angle estimation block and a speed control block. The analog part consists of a gate driver, which is able to sense the phase current of a motor. The sensorless algorithms adapted in this paper include a sliding mode observer (SMO) method that has high robust characteristics regarding parameter variations of PMSMs. Fabricated SMO chips detect back electromotive force signals. Furthermore, motor current-sensing blocks are included with a 10-bit successive approximation analog-to-digital converter and various gain current amplifiers for proper sensorless operations. Through a fabricated SMO chip, we were able to demonstrate rated powers of 32 W, 200 W, and 1,500 W.Keywords: Wide power range of motors, sensorless speed control, sliding mode observer driver IC, integrated gate driver.

“…Sensorless controls can be divided into observer-based motor models [2]- [4], and high-frequency signal injection [8], [10]. To operate motors, a sliding mode observer (SMO) method is implemented owing to the various rated motor powers with different motor model parameters, such as phase resistance, inductance, and pole [6]- [7].…”

This paper presents an FPGA-based (Field Programmable Gate Array) sensorless controller for Surface Mounted Permanent Magnet Synchronous Machines (SMPMSM). A hybrid sensorless controller combining the signal injection technique and a linearly compensated flux observer is proposed. Using a Delta-Sigma A/D converter and FPGA oversampling technique, this work realizes a high performance high frequency (HF) injection sensorless control method which needs lower HF current response and introduces lower acoustic noises. The linearly compensated flux observer, based on back electromotive force (EMF) is used for sensorless control in the high speed range. The flux observer exhibits high dynamic and steady-state performance and is robust to parameter variation. Using model-based design, with the tools of MATLAB/Simulink and Simulink HDL (hardware description language) Coder, the whole control system is designed and implemented in a single chip. Experimental results demonstrate that the developed sensorless controller has high performance in the whole speed range.Index Terms-Field programmable gate array (FPGA), flux observer, high frequency (HF) injection, model-based design (MBD), sensorless control, synchronous machine (SM).
