Embedded system design for field-oriented stepper motor control

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.
