2.項目實施情況
工軟公司仿真系統依托以能量、質量、動量守恒原理為核心建立的流網算法,采用“機理數學伯努利模型+虛擬DPU”技術,使之與和利時MACS系列DCS控制系統有機結合,具備操作培訓、熱控培訓、事故演練、控制驗證與優化、工藝學習與優化等功能,真實地模擬現場環境并正確反映有關環境參數對機組運行帶來的影響,為1000MW機組電廠的順利實施和現場實施人員的模擬操作應用奠定堅實的基礎。具備如下功能:HONEYWELL CC-TAIX01底板
n 工藝仿真:汽機、鍋爐、電氣、脫硫脫硝、精處理
n 事故評分:正常操作、事故處理、自動評分仿真
n 分組功能:可整體演練,亦可分組培訓
n 硬手操:盤臺硬手操、畫面軟手操
n 熱工培訓:工程組態、PID整定
由于采用虛擬DPU技術,仿真機與現場操作畫面及邏輯高度一致,仿真系統框架與實際現場數據對照關系如下圖所示:
immature. Many classical control theories and concepts need to be further extended to the analysis and design of fuzzy control system:
1) In terms of analytical structure analysis, the structure analysis of TS fuzzy controller needs to be extended to more general cases and MIMO controller; The limit structure theory of general Mamdani and TS fuzzy controllers needs further discussion; At the same time, the analytical theory of fuzzy control for complex systems needs to be further deepened. For example, hierarchical fuzzy control system can solve the dimension disaster of multivariable fuzzy controller, and has been proved to be a universal controller [72]. Therefore, it is necessary to analyze the structure of this kind of controller.
2) The results of fuzzy control stability analysis are still lacking. The current methods are somewhat limited. More general stability criteria, especially the easy to understand and widely used methods based on the analytical structure of fuzzy controller,
