This application report presents a solution to control a permanent magnet synchronous motor (PMSM) using the TMS320F2803x microcontrollers. TMS320F2803x devices are part of the family of C2000 microcontrollers, which enables the cost-effective design of intelligent controllers for three phase motors by reducing system components and increasing efficiency. With these devices, it is possible to realize far more precise digital vector control algorithms like the field orientated control (FOC). This algorithm’s implementation is discussed in this document. The FOC algorithm maintains efficiency in a wide range of speeds and takes into consideration torque changes with transient phases by processing a dynamic model of the motor.
This application report covers the following:
- A theoretical background on field oriented motor control principle
- Incremental build levels based on modular software blocks
- Experimental results
