Introduction to Kalman Filters - Feb 2018

Trying to reduce product costs often comes down to using cheaper components.  Unfortunately, as is often the case, using a cheaper part gives worse results. The graph on the left shows real data from us controlling the sharing between two nodes. On its own the sensors are far too noisy to provide reliable measurements for our control systems, and as you can see will waste energy unnecessarily. However using more advanced control techniques and filters such as a Kalman Filter, we can dramatically improve the performance.
