PID Control with FreeRTOS

In this episode, we delve into the fundamentals of control theory, focusing on PID (Proportional-Integral-Derivative) control. We explore what control systems are, why they are essential, and how they can be implemented using FreeRTOS. The video introduces basic concepts through relatable examples like thermostats and cruise control, then discusses the principles behind on-off control, proportional control, and PID control. We also demonstrate how to set up a PID controller using STM32 microcontrollers and FreeRTOS, including practical coding examples. This episode sets the stage for deeper dives into more robust control systems in future sessions.
