presently, most microcomputer governors adopt pid control law . the traditional pid control law cannot deal with the conflicts of stability, accuracy and speediness . so parameters auto-tuning on-line must be adopted if stable operations under all conditions wanted to be guaranteed 目前的水輪機(jī)微機(jī)調(diào)速器普遍采用pid調(diào)節(jié)規(guī)律,傳統(tǒng)的pid控制無(wú)法解決穩(wěn)定性、準(zhǔn)確性和快速性之間的矛盾,要保證系統(tǒng)在各工況下穩(wěn)定運(yùn)行,必須采用參數(shù)在線自整定技術(shù)。
