Model-Based Design and System on Chip Implementation of DTC and PWM Techniques

This paper presents the implementation procedure of three Pulse Width Modulation (PWM) techniques and a closed-loop motor control method using a model-based design approach. The implemented PWM techniques are the Sinusoidal Pulse Width Modulation (SPWM), Space Vector Pulse Width Modulation (SVPWM), and Selective Harmonic Elimination Pulse Width Modulation (SHEPWM), whereas the closed-loop motor control method is the Direct Torque Control (DTC). These techniques are implemented using a ZedBoard development board which contains a System on a Chip (SoC) Xilinx Zynq-7000. The procedure of implementing these techniques on the ZedBoard and required considerations are discussed. The model-based design approach facilitates rapid implementation without prior knowledge of HDL and ARM programming, which makes it advantageous for students and research work. To verify the integrity of the implemented designs, the ZedBoard is used to control an induction machine (IM), and the results are presented.
