Electric drive platform: Integration and control


T. Stolz

Semester Thesis, SS16 (10532)

For the development of advanced control methods for electric drives, a versatile test bench is being developed at IfA. It consists of a printed circuit board (PCB) containing the motor drivers, current and voltage sensors, as well as hardware for measuring the rotor angle, connected to an ARM-based embedded control platform. In this semester project the PCB was assembled and carefully tested, the connection to the embedded control board was established and low-level drivers that provide access to the hardware were developed. To ensure synchronization of the measurements and reduce the computational burden imposed on the microcontroller, interrupts and the direct memory access (DMA) controllers were used extensively. This and the scarcity of some peripheral functions necessitated a careful analysis and allocation. The functional resources were assigned, ensuring an efficient use of the dedicated hardware, while respecting the tight platform constraints and providing the flexibility needed to control electrical drives of various types. The implementation was tested, illustrating the correctness of the implemented timings and the proper working of the digital measurement-data transfers.
