Variable Frequency Sine Wave Using MATLAB Simulink #26 | Basics | Paramjeet Singh Jamwal | INFO4EEE

In this video, a sine wave of variable frequency (20 Hz for 0 to 0.1 sec, 40 Hz for 0.1 to 0.2 sec, and 60 Hz for 0.2 to 0.3 sec) is generated using MATLAB Simulink.

Hello Sir. Thank you for your video. It helps me a lot. What if I want to make variable input freq and voltage. Can I use ramp block? Because I need to make sure v/f constant with changing voltage and frequency

Hello sir, I need a help from you.
I want to make a variable frequency control isolated dc-dc converter. I have to design a process block that will take response from PI controller and then gemerate PWM signal to provide variable switching frequency for three phase inverter. How to do that? How I can generate the PWM signal of variable frequrncy so that it always remain in between a minimum amd maximum frequency?

I would be grateful to you if you could help me. 😓

hi, do you know how I can change the output frequency of a sine wave by using a lookup table in simulink? I really appreciate if you can answer me

fcn block is removed n matlab 2021. can you write the program in matlab function block for sin(2*pi*u(1)*u(2))

hi, can you explain how can we get sine wave with the frequency is varied from 1 to 20 Hz{ A frequency sweep with a
resolution of 0.05 Hz}?

Can you guide us with matlab code for the same example?

Hello Sir,
Thank you so much for this useful video!

Can we increase the values of the frequency in a linear manner or a logarithmic manner instead of selecting a specfing values (for example every 5 seconds like your video) ?
