Application of Linguistic Fuzzy-Logic Control in fast and sensitive technological processes

摘要

This paper presents the use of modern numerical methods such as Fuzzy Logic Control for control of fast and sensitive non-linear technological processes with sampling period 0.01 [s] or less. The paper presents a real application of the Linguistic Fuzzy-Logic Control, developed at the University of Ostrava for the control of physical models in the Intelligent Systems Laboratory. The paper presents an example of a sensitive non-linear model, such as a helicopter model and obtained results which show how modern information technologies can help to solve actual technical problems. The paper shows how the used technology can help people easily describe the control strategy. A special method based on the LFLC controller with partial components is presented in this paper followed by the method of automatic context change, which is very helpful to achieve more accurate control results. This technology and real models are used as a background for problem-oriented teaching, realized at the department for master students and their collaborative as well as individual final projects.
