Issues and improvements of hardware/software co-design sensorless implementation in a permanent magnet synchronous motor using Veristand

This paper is focused on the implementation of a field oriented control of a permanent magnet synchronous in the emerging rapid control prototyping tool Veristand through a National Instruments PXI device. The device is composed of a FPGA and a controller so the hardware/software co-design is discussed in order to optimize the control system. The algorithm is solved by calculating the position of the rotor in two ways: firstly with the resolver sensor and secondly with a signal injection sensorless method to compare the position results. Both configurations are simulated to tune the system properly, and finally they are tested experimentally with the mentioned control platform. Taking advantage of the Veristand hardware/software co-design flexibility, the sensorless method was implemented in two ways in order to demonstrate the flexibility of the control system and compare the results of both solutions.
