Raspberry Pi LESSON 59: Improved Pan/Tilt Tracking Control Algorithm


In this Video Lesson we show an improved control algorithm for tracking an Object of Interest in OpenCV. We develop a simple example of Proportional control, where the correction signal is proportional to the error signal. We show this is a much improved algorithm over our earlier one, which simply applied 1 degree corrections independent of the size of the error. The code we develop in this lesson is included below for your convenience.


9-Axis IMU LESSON 26: Understanding PID Control systems with Arduino


In this lesson we use our BNO055 9-axis sensor, and our pan-tilt servo mount to create a self-leveling platform based on a classic PID control system. The video takes you step by step through the theory behind a PID controller, and then demonstrates a practical example in hardware. In the video we develop the code below.
