great video

[@paranmanjang_]

You made my day! Thanks!

[@yossifahmed1083]

please make a postion control of DC motor using simulink arduino !!

[@paranmanjang_]

I’ll try making it next time when I have time. Other than speed control and handling encoder values, most of it is quite similar, so it might be a good idea to apply it on your own as well.

thanks bro

Any time

Could the PID tuner be used to obtain the values for Kp, Ki, and Kd?

[@paranmanjang_]

That’s right. It was used to determine the values of Kp, Ki, and Kd. Once the values are finalized, you can use them by putting them into the constant value. I included it to demonstrate how to perform PID tuning. Looking at it now, the explanation seems a bit lacking. You can think of Kp as being used to increase or decrease overall responsiveness, Ki as being used when the system is unable to follow the target, and Kd as being used to reduce the magnitude of oscillations.

How to get the position of the motor using the encoder ?

[@paranmanjang_]

You can divide 360 degrees by the PPR (pulses per revolution) of the motor. In my current motor setup, 42 pulses are detected for a full 360-degree rotation. This means that for every increase of 1 in the encoder value, the angle increases by approximately (360/42 = 8.57) degrees. If there is a gear, you simply divide by the gear ratio. I’m planning to upload a video related to this (PID position control) soon, so I’ll tag you when it’s uploaded.

I’ve explained this in detail in the PPT for “DC Motor Control Part 2,” so please refer to that.

i really want bts7960 motor driver with simulink

[@paranmanjang_]

I checked the datasheet, and it seems like you can connect it as follows: Use LPWM instead of IN1 and RPWM instead of IN2. Connect ENb to the PWM pin. Then, connect OUT1 and OUT2 to M+ and M-, and adjust the direction accordingly. It should work the same way.

[@paranmanjang_]

I recommend starting from Part 1 and following along. In Part 1, it focuses on setting the direction correctly. In Part 2, it calculates the RPM based on the encoder, and by reviewing and applying Part 3, it should work.
