In this thesis is developed and analyzed the control of speed of permanent magnet machine fed up from back-to-back PWM three-phase converter supplied from the grid, as part of the project of a testbench for testing the commercial inverter. Methodology to the derivation of the control of the system, including control of the speed of the permanent magnet machine and maintaining the stable voltage reference on DC link capacitor, is explained. The obtained control strategy is simulated in Simulink simulation tool of Matlab software package. Thesis is also covering several aspects of the hardware design of the application, such as sizing of the components of the power stage (machine, DC link capacitor, lters), design of the hardware interface between power stage and digital signal processor and control implementation in DSP written in C code. An experimental test of the control of the output of the three-phase IGBT module generated from DSP is performed for the sake of validation of the design of the PCB interface and the con figuration of DSP.
