Hello all,
I am improving the performance of Vector control IM drive using PSO +FLC.For this, I am using ready-made simulink model of the Vector control of AC Motor Drive (power_acdrive.slx). In order to increase the speed of simulation I tried all suggestions like disabling zero-crossing, changing solver type (decrease solver order), increasing the number next to 'Number of consective steps', reducing/increasing Max.step size, run the model in accelerator mode etc etc... but found slight/no change in speed of simulation!!
I am running this simulink model using Matlab 2017a on my laptop having details as : Intel® Core ™ i3-2328CPU @ 2.22GHz, 4.00GB RAM, 64-bit OS, Winodows 7 ultimate. I am using variable-step ode45(Dormand-Prince) solver. Your suggestions are most welcome about how to increase the speed of simulation(particularly for this simulink model)

Hi
You can try:
  • a variable step solver: adjust absolute and realtive tolerances
  • a fixed step solver: use a few different fixed step-size
Good luck
