“…The huge amount of computing of Observer Status Method limits its application. With the rapid development of compute technology and emergency of DSP with high-speed computing power, Observer Status Method has been widely used, and more novel control method derived on the basis of it [1][2][3][4].…”

With the widely use of Permanent Magnet Brushless DC Motor (BLDCM) in many fields, the superiority in the control method of position sensor-less is more and more obvious. In this paper several control methods of position sensor-less for BLDCM are presents, and a novel technique, the method of speed-independent position function, is introduced to detect the rotor position of BLDCM. This method may detect the rotor position from almost zero speed to high speed, and may also give the commutation time.

“…Generally speaking, the actual industrial plants, especially the major equipment used in basic manufacturing, such as Tunnel Boring Machine (TBM) (Yang et al, 2019;Li et al, 2010;Zhao et al, 2015) and PMSM, often have strong nonlinear characteristics. Therefore, the study of nonlinear system state estimation has been a hot topic during the past several decades (Elbuluk and Li, 2003;Hicham et al, 2004;Gan and Wang, 2015;Liu, 2018).…”

PurposeThe purpose of this paper is to investigate the design method of partial observer canonical form (POCF), which is one of the important research tools for industrial plants.Design/methodology/approachMotivated by the two-steps method proposed in Xu et al. (2020), this paper extends this method to the case of Multi-Input Multi-Output (MIMO) nonlinear system. It decomposes the original system into two subsystems by observable decomposition theorem first and then transforms the observable subsystem into OCF. Furthermore, the necessary and sufficient conditions for the existing of POCF are proved.FindingsThe proposed method has a wide range of applications including completely observable nonlinear system, noncompletely observable nonlinear system, autonomous nonlinear system and forced nonlinear system. Besides, comparing to the existing results (Saadi et al., 2016), the method requires less verified conditions.Originality/valueThe new method concerning design POCF has better plants compatibility and less validation conditions.

“…And the ideal commutation point is 30 electrical degree shift the zero-crossing point (ZCP) of the non-excited phase back-EMF. There are many methods based on this idea [7], including detecting back-EMF directly, back-EMF integration, building back-EMF observers like Kalman observer [8] or sliding-mode observer [9] and so on [10,11]. However, most of these methods work well only in a narrow range of speed as the amplitude of Back-EMF is related to speed.…”

-A new sensorless control strategy for brushless DC( BLDC) motors is proposed in this paper. This technique builds a rotor position-related flux function, which is independent of the speed. By observing the flux function, the information of rotor position and commutation can be obtained. As the function is not speed-related, this control process can be used in a wider range of speed and improves the motor's performance during startup. An experimental test bad based on TMS320F2812 has been built, and the experimental result indicates that the motor achieves a smooth starting-up and stable phase commutation with the proposed control strategy.
