Model based design controller for the stepper motor

The motivation of this work is to make a library for an embedded system useful in implementing of the field-oriented PM stepper motor control. The tool is based on DSP processor board, a hardware component oriented for embedded applications and Matlab/Simulink environment. Matlab is a standard in rapid prototyping of the control applications, but it doesn´t have an adequate hardware support. The target controller is connected via serial port to the host PC computer. An integrated development toolbox having a distributed nature and real-time requirements was developed. It is useful for rapid control prototyping and for hardware-in-the-loop simulations. The full functionality of Matlab/Simulink can be used for parameter´s visualization without interrupting or impeding the real time control process of the embedded microcontroller. Finally, the field-oriented for a two-phase PM stepper motor application is presented in order to demonstrate the effectiveness for this real time embedded controller.
