Abstract
Fuzzy logic technique is an innovative technology used in designing solutions for multi-parameter and non-linear control models for the definition of a control strategy. As a result, it delivers solutions faster than the conventional control design techniques. This paper thus presents a fuzzy logic based-temperature control system, which consists of a microcontroller, temperature sensor, and operational amplifier, Analogue to Digital Converter, display interface circuit and output interface circuit. It contains a design approach that uses fuzzy logic technique to achieve a controlled temperature output function.
Highlights
Human brain has an imprecise way of reasoning and has a high adaptive control approach
Computers cannot do so because its logic is based on approximate reasoning in a more familiar Boolean forms of logic used in conventional set theory
Fuzzy logic allows the use of labels like “slightly”, “moderately”, medium, and “very” so that statements may be made with varying degree of precision
Summary
Human brain has an imprecise way of reasoning and has a high adaptive control approach. Fuzzy logic allows the use of labels like “slightly”, “moderately”, medium, and “very” so that statements may be made with varying degree of precision This flexibility is useful in coping with the imprecision of real-world situations such as designing precision environmental control systems. Fuzzy logic is widely used in machine controls, as it allows for a generalization of conventional logic and provides for terms between “true” and “false”, like “almost true” or “partially false” This makes the logic not to be directly processed on computers but must be emulated by special codes. Its technology provides room for graphical user interface, which makes it understandable by people who do not have process control backgrounds Another key significance of a fuzzy logic-based control design is the ability to automatically and smoothly adjust the priorities of a number of controlled variables [2]. Fuzzy logic is spreading applications in the field of telecommunications, in broad band integrated networks, based on ATM Technology [4]
