Fuzzy Demo
• Demo of fuzzy logic inference system implemented on Microsoft .NET Micro Framework, deployed on the ATMEL ARM Evaluation kit
• Fuzzy Inference Engine, with 2 inputs and 1 output,
based on laboratory data
Step 1 : Fuzzy Sets Configuration
• For each Fuzzy Variable and each Fuzzy Set, the Universe of Discourse may be configured separately
• The selected Fuzzy Set is shown in red, and depicts instantly the applied values.
• All fuzzy sets are considered to be trapezoids defined by four points, which may be configured as needed
• Demo application deployed on ATMEL DK
Step 2 : Fuzzy Rules Configuration
• For each combination of the inputs, the value of the output is configured in terms of fuzzy values.
Step 3 : Fuzzy Inference - Defuzzification
• The graphical representation of the input signals is based on experimental data
• The two inputs are applied to the inference engine, in order to calculate the output.
• For every pair of input values at any given time
• the analog inputs are fuzzilied,
• the fuzzy rules are applied, and
• the output is defuzzified to a crisp value.
• Configuration variations, result to different output waveforms.
