Automatic Acquisition of Local Fuzzy Rules by DNA Coding in new Composition Reasoning Method |
| Abstract |
In this paper, the new composition method of global and local fuzzy reasoning concepts is proposed to reduce, optimize and automatically acquire the number of rules, without any lose of the general performances in conventional fuzzy controllers. In order to control the interaction between global reasoning and local reasoning, the DNA coding algorithm is introduced to the local fuzzy reasoning of the proposed composition fuzzy reasoning method. The method is applied to the real liquid level control system for the purpose of evaluating the performance. The simulation results show that the proposed technique can control the system with higher accuracy and automatically acquire the fuzzy rules with more feasibility, than the conventional methods. |
