Usually we linearize them approximately in industrial process, but in some cases this ca n ' t satisfy the request of automatic control which makes us consider the nonlinear factors in the industrial process. in practical process of power plants the typical structure nonlinear case is dead - zone and the latter case is the nonlinear variance of objects ' parametres with the changes of working condition. the nonlinear research is parallel with the linearity and adaptive method can be used to deal with nonlinear cases. in this paper two adaptive control methods are used to solve the problems brought by the dead - zone of boiler negative pressure system and the nonlinear changes of the milling system ' s character parameters, which achieved good results
在生產中通常對非線性作近似線性化處理；但在某些情況下線性近似達不到自動控制的要求，必須對生產過程中的非線性情況進行考慮。在火電廠的實際生產中，典型的結構非線性之一是死區；參數非線性多發生在控制對象特性隨工況變化而變化，表徵其特徵參數變化呈非線性。非線性控制的研究與線性控制的研究是并行的，針對非線性情況，可以採用自適應的控制方法。 -
