Adaptive PID Controller For DC Motor Speed Control

I am currently working on a project titled “Speed Control of a DC Motor Using an Adaptive PID Controller.” However, during the control process, I have encountered several issues that cause the motor to operate unstably. Specifically, the plant does not closely follow the reference model at low and medium speed ranges. Therefore, I would like to ask if anyone has a Simulink diagram related to this topic that I could refer to.

Hi @Mnh, Thanks for sharing the details about your project. However, the message could use a bit more information to help others provide effective support. For example, could you clarify:

What specific issues or errors are you encountering during simulation or implementation?

What kind of adaptive PID controller are you using (e.g., gain scheduling, model reference adaptive control)?

Are you implementing this in a purely simulation-based environment or also on hardware?

Can you share a basic overview or screenshot of your current Simulink model setup?With this information, the community will be in a better position to assist you. Looking forward to more details!

Without a sample model we can not really point to any specific problem. You can start building the simulation model using existing examples in Simscape Electrical. This example shows a cascade speed-control structure for a DC motor:

Simscape Electrical also provide a discrete-time PID-based model reference adaptive control that can be used in the example I mentionded:
