Hello! I want to print data just like the Serial Monitor in the Arduino IDE in Simulink. Is there a Simulink block for this? Why do I want to do this? It's because I want to connect it to ROS 2.

i'm using STM32 nucleo board and it doesn't have encoder block. is there an solution ?

@paranmanjang_ 6 күн бұрын

@@hongsethya4932 I think you can make your own. Check your encoder's data sheet first!

@paranmanjang_ 6 күн бұрын

@@hongsethya4932 Most encoder lines have two or three signal lines, usually sigA, sigB, direction, or the calculated count number or direction. Therefore, it is recommended to first check the signal output specified in the motor encoder’s data sheet and then bring those signals into the Arduino as input signals to build the system.

Very good as you are using MATLAB/Simluink and embedded systems, this is more serious than just using the other platforms as more serious users will come to you. One suggestion though: It is better if you start a real world robotic project like a rover or anything you like and show case the power MATLAB/Simulink and the embedded systems likes Arduino, ESP and/or Raspberry Pi. 👍👍👍👍

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.

i really want bts7960 motor driver with simulink

@paranmanjang_ 27 күн бұрын

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_ 27 күн бұрын

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.

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

@paranmanjang_ Ай бұрын

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.

@paranmanjang_ Ай бұрын

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

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

@paranmanjang_ Ай бұрын

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 can you move the slider gain while monitoring and tuning? It became grey and could not be change when i try it.

@paranmanjang_ Ай бұрын

@timothymak9129 Check MATLAB’s hardware settings first! And check for any error messages while building.(Monitor and run) Go to Hardware -> Code Generation -> Build Configuration: Faster Run. If you can’t use it, try the ‘slider’ block instead. There are many other ways to do it. For other videos in the DC motor control series, the implementation was done using a slider, so please refer to those! :)

Hey Donghwa, great job. From what I understand PWM and Pulse generator are two distinct things. Have you tried to get PWM on the scope ? Based on sg90 datasheet and your great explaination 0 deg corresponds to 1 % of the duty cycle and for 180 deg duty cycle is basically 10 %. how do i achieve this control with Matlab ? Let me know what you think. Cheers.

@paranmanjang_ Ай бұрын

I don’t have an oscilloscope, so I couldn’t check the PWM signal directly. However, I realized that I might be able to check the pulse values using an Arduino signal. I’ll try it out, and if I get any results, I’ll let you know.😊

How could I do it with a 360 servo?

@paranmanjang_ 5 ай бұрын

If there is any sensor that can detect the angle of the motor, it is possible to control it, whether it is a servo motor, a DC motor, or a three-phase motor.
