How can I generate a variable frequency triangular wave in Simulink?

I want to input the frequency externally, it should give the triangular wave of that frequency

Hi, You could use the following setup in simulink

1. use wm as variable frequency input

2. set integrator in Wrap State mode with upper and lower value

3. use abs and level shifter to convert sawtooth into triangle waveform

Hope this could help.

excuse me brother could you upload the matlab file i will be really appreciated

I meet the same question.However,I can not construct the whole model,Please upload the total matlab file or send it to my email [e-mail],please!

i'm sorry, what is the utility of gain 1 and 2?

[Alper]

Hello CAC, what is 'p' in block named Gain2? Could you send me this file?

Thank you in advance.

Hello CAC, can you explain what is p and also send me this file? Thank you.

Привет! Я сделал вот так. Но заметил, что если частоту менять слишком интенсивно, генератор начинает лагать. Например управляющая частота меняется от 100 до 500 kHz, а на выходе проскакивают мегагерцы. Ищу решение.

I could not find the triangle module in simulink ,could you send the total model in picture to my email,it is [e-mail]
