Fuzzy logic is a problem-solving control system methodology that lends itself to implementation in systems ranging from simple, small, embedded micro-controllers to large, networked, multi-channel PC or workstation-based data acquisition and control systems. It can be implemented in hardware, software, or a combination of both. Fuzzy logic provides a simple way to arrive at a definite conclusion based upon vague, ambiguous, imprecise, noisy, or missing input information. Fuzzy logic's approach to control problems mimics how a person would make decisions, only much faster.

Without getting into long winded explanations, fuzzy logic allows for deductions on imprecise values or, put another way allows a system to deliver a single answer for a range of values. For example: A machine can be programmed to detect if a container is empty or full. A range of zero to fifty per cent can be programmed to deliver an ‘empty’ response and fifty one to one hundred per cent as ‘full’. Essentially the system does not deliver a precise result such 61.5% full or 38.5% empty. This is a very basic explanation. Check out the following:
