As we know, for an inverter we need vcontrol and a triangle wave to produce gate pulses. Matlab simulink has the sawtooth sequence but we need Isosceles triangle.
Start by fully describing the function you wish to generate as simple function of time.
Dr Barrie Gilbert
i tried to produce it but in some high frequencies the wave form will not be the same as low frequencies
If you are generating the function in a mathematical environment such as MatLab or a circuit simulation platform, a triangular voltage waveform can be made independent of frequency, so your response puzzles me. What is meant by "some high frequencies"? As engineers we are expected to use very precise language whenever possible.
If you tell me EXACTLY what you wish to achieve, I expect I can help you.
Mr Barrie Gilbert
my problem has solved,actually was with the triggering voltage of inverter,Thank you for your guidance, it really helped me.
my master thesis is about Field oriented control of Synchronous Reluctance Motor,at first I should simulation this motor in Matlab/Simulink but the block of this motor doesn't exist,please guide me about the complete model of this motor
Best regards
I think what you are working on is outside of my field of experience. I don't know how to model a motor in Simulink. It is a complex electromechanical device and the model would need to take many details into account, including the load conditions. I hope there is someone else out there than can take it from here.
