Hi all,
I am just wondering how do you connect a Triangle wave (or input a triangle wave) to an op-amp circuit ? The triangle wave models (sawtooth, triangle) are build in the Specialised Power System toolbox, which is in the form of a Simulink signal. I tried to use a Simulink-PS converter and connect the PS side to a Controlled Voltage Source, and had no luck. Anyone has any guide ?
Thanks

your method is correct. this image shows a model that has been tested. what is the problem exactly? any error?

you're welcome. in order to create a variable-frequency signal, you can use 1d look-up table. define your function in one period vs angle from 0 to 2*pi. now your look-up recieves angle. you can provide an integrator to its input that integrates angular frequency and provides the angle. this way you can have a variable-frequency signal with any frequency arbitrary at its input.
you can also modify the existing saw-wave generator in simulink library as the above procedure. but before that, you must disable its link, or you can Ctrl+U on it andcopy its content to another subsystem and attempt to modify it.
