outline
Outline
  • Motivations
  • The concept of system identification
  • The improved algorithm
  • Simulations and Discussions
  • Conclusions and Future Works
motivation
Motivation
  • Only I/O data
  • Model construction
  • I/O relation
  • Modification
coarse fuzzy modeling
Coarse fuzzy modeling
  • Fuzzy C-Regression Model (FCRM)
  • Premise parameters generation
  • Consequent parameters generation
example 1 2
Example 1 (2)

The optimal parameters

conclusions and future works
Conclusions and Future Works
  • 架構精簡,彈性大
  • 易於在電腦上實現
  • 不錯的運算效率和較佳的近似結果
  • 有較佳的能力去描述未知系統
  • 改進FCM方法不足之處
  • 以其他的最佳化方法取代最陡坡降法
