A new mathematical model for the command sequence generator of a two-phase hybrid stepper motor

Modeling processes before physical experimenting is a necessary a preliminary stage for verification and validation of a proposed algorithm of command and control. Elaborating of these algorithms for microcontrollers through a written code, compiled and uploaded into memory consumes valuable time. Reducing this spent time can be obtained through special developed compilers for different types of microcontrollers in Matlab®-Simulink®. In this paper are presented new mathematical models which describe the command sequences of a stepper motor. These mathematical models are simulated within the Matlab-Simulink software and validated through an Arduino Uno development board (with Atmel microcontroller). The obtained results through software modeling are confirmed by experimental results.
