Implementation of a rotor position determination system for a switched reluctance motor in FPGA devices

The paper presents three rotor position detection modules implemented in FPGA devices. The modules are characterized by different methods of implementation and were developed for use with a switched reluctance drive. They operate in the following modes: sequentially synchronized with a clock signal, concurrently synchronized with a clock signal, and asynchronously. Simulated and measured delays introduced by these modules in the FPGA device are presented.
