Currently, I am using MATLAB 2014a Simulink version. I want to generate PWM pulses for a switch. I am using repeating sequence generator and sinusoidal signal from sources library. Both are from simulink blocks category only. When I run the program.. following error appears.....
Sign in to comment. Answers (1) Shreshthon 20 Aug 2024 0 Link Hello Yash, I understand that you want to control the motor driver by sending the I2C commands to the module from MATLAB. For this you can install the"Simulink support package for Arduino"where the availible (PCA9685)...
You can connect the models. You would typically connect them with a dc link with a battery. Here is a shipping example of a single phase inverter that you could also use as a starting point:https://www.mathworks.com/help/physmod/sps/ug/single-phase-pwm-inverter.html ...
For context, the aim is to create a PFM waveform that increases in frequency with respect to time, increasing from a 1-to-2 mark space ratio to a 1-to-1 whilst keeping the 'on-time' of the signal constant. Ideally, the waveform should look something like this at the s...
MATLAB Online で開く Dear community, I’ve got a problem, even if I try many things; I have to admit that I don’t know how to solve it. It’s the first I face of timing problem. The problem: I want to generate a pwm with a variable ...
Matlab s-functions seem scarier than they really are. Understandinghow Simulink worksand what goes behind the scenes when you simulate helps learning s-functions. In this blog I’ll show you how to write a simple s-function to generate variable width pulse train (variable width PWM or variable...

My suggestion is to leave only the ZVM toolbox in the MATLAB paths in order to ensure that the correct Simulink library is used. Anyhow, if you are interested in how Position Observer works, i may suggest to have a look at this topic: https://community.nxp.c...
