Amazingly, to this day, there are still a very significant number of analog PID controls sold every year. Because of its simplicity, many robot designers have adapted software PID controls for servo ...

New Book Release The new book, PID-Based Practical Digital Control with Raspberry Pi and Arduino Uno , is about using the Raspberry Pi 4 and Arduino Uno in PID-based automatic control applications.

A diagram can provide us a much more intuitive understanding of how this math works when applied to a servo motor. Figure 1 illustrates the block diagram of a linear servo PID control system.
