This article discusses the method of indirect measurement of speed based on the information received from the rotor position sensor. The method is to implement numerical differentiation using polynomial interpolation. The paper evaluated the accuracy and speed of the method of polynomial interpolation. Speed is defined for modern 32-bit microcontrollers Microchip dsPIC33F and Atmel AVR32UC.
