 無論是現(xiàn)代控制理論還是大系統(tǒng)理論，其分析、綜合和設(shè)計(jì)都是建立在嚴(yán)格和精確的數(shù)學(xué)模型基礎(chǔ)之上的，但目前人們對(duì)大規(guī)模、復(fù)雜和不確定性系統(tǒng)實(shí)行自動(dòng)控制的要求不斷提高，應(yīng)運(yùn)而生了智能控制理論。所謂智能控制是指那種無需或盡可能少的人的干預(yù)就能獨(dú)立地由智能機(jī)器實(shí)現(xiàn)其目標(biāo)的自動(dòng)控制，是一種將人工智能技術(shù)與經(jīng)典、現(xiàn)代控制理論相結(jié)合的控制，智能控制系統(tǒng)是由智能機(jī)器對(duì)生產(chǎn)過程自動(dòng)控制的系統(tǒng)。

  直接Te控制技術(shù)概述
  直接Te控制技術(shù)是繼矢量控制后交流調(diào)速領(lǐng)域一門新興的控制方法，其特點(diǎn)是采用空間電壓矢量的分析方法，直接在定子坐標(biāo)系下計(jì)算并控制電動(dòng)機(jī)的Te和磁通，采用定子磁場(chǎng)定向，進(jìn)行開關(guān)控制，產(chǎn)生PWM信號(hào)。系統(tǒng)通過保持磁鏈恒定，對(duì)Te直接控制，因此控制性能不受轉(zhuǎn)子參數(shù)的影響。將智能控制理論應(yīng)用于直接Te控制是目前較好的研究方法。
直接Te控制的基本原理
逆變器可以看成是三組開關(guān)Ｓ[(0，0，0)，(0，0，1)，…，(1，1，1)]，相應(yīng)的電壓矢量有8種(u0，u1，...，u7)，其中6種為非零矢量(u1，u2，…，u6)，兩種為零矢量(u0，u7)。電動(dòng)機(jī)的定子磁鏈?zhǔn)噶繛?/span>
φ1＝∫(u1－R1i1)dt (1)
式中 u1——定子電壓；
i1——定子電流；
R1——定子電阻。
忽略在定子電阻上的電壓降，可得
φ1＝∫u1dt (2)
這表明：當(dāng)電動(dòng)機(jī)定子繞組上施加空間電壓矢量u1(SASBSC)在Δt時(shí)間內(nèi)，在電動(dòng)機(jī)氣隙內(nèi)產(chǎn)生，相同方向的磁鏈
ΔφS1＝u1(SASBSC)Δt (3)
即ΔφS1的大小與|ｕ1|的大小和作用的時(shí)間Δt有關(guān)，但其方向則可能與該電壓作用前已存在的磁鏈φS的方向不同，其總磁鏈ΔφS1應(yīng)為二者的矢量和。由于Te直接控制的逆變器按一定規(guī)律變化的開關(guān)狀態(tài)，因此，如果合理地選擇各空間電壓矢量，就有可能獲得幅值近似不變而又旋轉(zhuǎn)的定子磁鏈，即所謂的圓形軌跡定子磁鏈。直接Te控制系統(tǒng)結(jié)構(gòu)框圖如附圖所示。
