Basketballbot: Education Level Development Of A Fuzzy Controller For A Linear Motor Under Saturation Limits, David L. Mcpherson
Basketballbot: Education Level Development Of A Fuzzy Controller For A Linear Motor Under Saturation Limits, David L. Mcpherson
Honors Theses
Fuzzy logic seeks to express human modes of reasoning and decision making in a mathematical form. This is evident in its terminology such as “linguistic variables” defined over a “universe of discourse”. By taking human expressions such as “very high” or “pretty cold” and defining them in a mathematical context, expert operator knowledge can be transferred from verbal descriptions into automated control algorithms regardless of the operator’s familiarity with control systems. Because fuzzy logic is designed to be easily comparable with human thought, it makes an excellent first exposure to control systems concepts to high school and undergraduate students. Additionally, …
