Hi everyone, I am pretty new at this. I made a Simulink project that can control the direction of the motor and the PWM of the motor. What I wanted to do is to read encoder and measure the speed from it. I tried some algorithms I found on the internet but they don't work. When I increase/decrease the speed, the output of the algorithm changes absurdly. I would really apreciate any help. Thank you.

Note: I tried reading encoders from Analog input and Digital Input. Nothing changes.

Blocks:

Output(60 PWM):

Output(90 PWM):

Output(120 PWM):

Hi Vedat,

We have many resources to help you get started on controlling servo motor using Arduino Hardware. You may refer to this motor control example for more information. https://www.mathworks.com/help/supportpkg/arduino/ref/servo-control.html

To measure the encoder signal such as speed and angle, we have Arduino hardware support package - Encoder block to help you measure incremental position and direction of rotating motor.

This link provides you an overview of running Simulink models on Ardunio boards.
