Python Script (3): Run System Simulation
R. Tanner FEMAG and PLECS 6 / 6
Send XML-RPC-Requests to the running PLECS instanceto load system model, start simulation and process results:
plecs_model = "pmsm-mtpa-fw"with xmlrpc.client.ServerProxy(
"http://localhost:1080/RPC2") as server:server.plecs.load(os.path.join(os.getcwd(),
plecs_model + ".plecs"))opts = {'ModelVars ': {'Vbat': 500}}result = server.plecs.simulate(plecs_model , opts)
time = result['Time']i1 = result['Values '][0:3]psi = result['Values '][3:5]wm = result['Values '][5]torque = result['Values '][6]
Conclusion:With Python a fast and easy coupling of PLECS andFEMAG can be realized which allows a detailedsimulation and optimization of complete drive systems.
