Description: The purpose of this document is to provide fundamental high-level information
about the Mac OS X core operating-system architecture. It also provides
background for system programmers and developers of device drivers, file
systems, and network extensions. In addition, it goes into detail about topics of
interest to kernel programmers as a whole.
This is
not
a document on drivers. It covers device drivers at a high level only. It
does, however, cover some areas of interest to driver writers, such as crossing the
user-kernel boundary. If you are writing device drivers, you should primarily read
the document
Inside Mac OS X: I/O Kit Fundamentals
, but you may still find this
document helpful as background reading.

Description: We propose a position sensorless control scheme for a four-switch, three-phase brushless DC motor drive, based on
the zero crossing point detection of phase back-EMF voltages using newly defined error functions (EFs). The commutation instants
are 30° after detected zero crossing points of the EFs. Developed EFs have greater magnitude rather than phase or line
voltages so that the sensorless control can work at a lower speed range. Moreover, EFs have smooth transitions around zero
voltage level that reduces the commutation errors. EFs are derived the filtered terminal voltages vao and vbo of two low-pass
filters, which are used to eliminate high frequency noises for calculation of the average terminal voltages. The feasibility of the
proposed sensorless control is demonstrated by simulation and experimental results.-We propose a position sensorless control scheme for a four-switch, three-phase brushless DC motor drive, based on
