Description: 本设计将对烘干机的温度控制予以研究。烘干机的结构虽然比较简单，但烘干过程是非线性、时变性和多变量的。在烘干过程中由于受各种不确定因素的影响，难于建立精确的数学模型。虽然自适应、自校正控制理论可以对缺乏数学模型的被控对象进行识别，但这种递推法复杂，实时性差，对烘干机水分的控制难以取得较好的控制效果。本设计将模糊控制理论最新应用于干燥的控制系统，以单片机为核心的模糊控制器将模糊逻辑语言控制策略变为有效的自动控制策略。在数字单片机上用模糊控制算法编制软件程序来实现对烘干过程的模糊控制。-This design will study to the dryer temperature control. The structure of the drier is simple，but the drying process are non-linear, changing with the time and multi-variable. Due to the impact of the uncertainty factor, it is hard to establish the precision of the mathematic model. Though the theory can recognize the controlled object which short of them a thematic model, it is hard to useful control effect because of the complication and the disadvantage in the real- time control. The present design will make controls theory most newly to be applied to the dry control system, the fuzzy controller which takes Micro Control Unit as the core will make the fuzzy logic language control strategy to a effective automatic control strategy. Realizes on the digital Micro Control Unit with the fuzzy control algorithm establishment software procedure to dries the process of fuzzy control. Platform: |

Description: ADVANCED FUZZY CONTROL OF THE TEMPERATURE IN THE TEST-The paper deals with a systematic approach to the control system design with a final goal to efficiently control
some living conditions in a test chamber. The first step of each systematic approach is mathematical modelling. It was
based on theoretical approach, which means that the model was developed on the basis of physical laws, energy
equilibrium laws etc. The mathematical model was implemented in MATLAB Simulink environment as a simulator
entitled KAMRA. The structure is modular, the robust numerical algorithms give accurate results and fast simulation
runs. As simulator is implemented in MATLAB environment, it is very easy to implement arbitrary pre simulation and
post simulation processing. The validation was made by real measurements as test chamber is equipped with all needed
sensors. The developed simulator gives an ideal environment for the design and validation of different control structures.
Four fuzzy logic controllers were proposed for efficient control of indo Platform: |

Description: Maximum power point tracking using a fuzzy logic control scheme.This paper proposes an intelligent control method for the maximum power point tracking
(MPPT) of a photovoltaic system under variable temperature and insolation conditions. This method
uses a fuzzy logic controller applied to a DC-DC converter device. The different steps of the design
of this controller are presented together with its simulation. Results of this simulation are compared
to those obtained by the perturbation and observation controller. They show that the fuzzy logic
controller exhibits a much better behaviour. Platform: |
