Summary

In this chapter, we've introduced fuzzy logic and fuzzy control. The fundamental fuzzy operators were defined using three very different applications (packet flow, target-tracking, and charge control). Hedge functions were also introduced as a linguistic modifier to existing fuzzy membership functions. A sample application of battery charge control was then detailed to identify how the membership functions and control elements were created using fuzzy semantics. Sample code was used to illustrate this concept, including a set of generic fuzzy logic APIs. Finally, some of the advantages of fuzzy logic were discussed including simplification and cost reduction of the hardware embodiment.
