Ansys TwinBuilder CO-Simulation with Matlab for PMSM control

  Hello, i try to simulate a PMSM for my matlab control structure. I already have the simulation running and can read out voltages and currents between the programs without any problems. But now I also want to read out the speed and angle from the Maxwell model. My problem is in the MotionSetup, I honestly don't understand the correct wiring. I have already tried various possibilities. Neither the readout of Omega and PHi directly from the FEA block nor the measurement blocks provided me with an understandable angle. I initially used a three-phase sine wave voltage with 3 Hz from Matlab as the voltages. Any helpful suggestions would be greatly appreciated

  Hello Philipp Bolsinger,
  There is an example for PMSM control in AEDT installation folder in C:\Program Files\AnsysEM\v241\Win64\Examples\Twin Builder\Applications\PowerSystem\PMSM_SpeedControl_EMI.aedt. You can use "File > open examples" to find it too.
  You have to use speed and angle from Motion to determine frequency and phase angle for the controller. Please login customer portal to find more information if possible.
  1). Co-simulation between Maxwell and Twin Builder/Simplorer
  2). Simulink Co-Simulation with Simplorer
