PMSM Mathematical Motor Model
显示 更早的评论
cification voltgae=50,max speed=10000 RPM, fulx Linkage=0.00459,Motor Poles=22,Internal Resistance =0.016, D-Q axis inductance=0.000015 mH,interia=0.0000231 .when i operate at the low frequeny 10 volt it works fine, at higher frequency it is making oscillation in the volatge current torque and speed.(No control Method is used here, just purely mathematical model and supply voltage and theta as the feedback to the clark and park transfromation )

What is your question? (About MATLAB!) Are you surprised that something oscillates, or goes unstable? That can happen easily enough. Not only that, but we have no knowledge that what you even did was correct in terms of code, since we cannot see inside your computer, and you show no code. So what are you asking? What can you expect for an answer here?

I have assumed the Linear Magnetic model with a balanced three-phase system and used the parameters you provided. I did not observe any oscillations; there is some transient behavior initially, but the system reaches a steady state afterward.
