预测控制是一种计算机控制算法,因其建模简便、易于在线实施,在工业控制中得到了越来越广泛的应用。动态矩阵控制是一种应用广泛的预测控制算法。本文将动态矩阵控制算法进行了改进,并将其应用于水轮机调节系统,对多种型式的机组转速调节进行了研究。动态矩阵控制改进算法使得模型可较早截断,避免了一般动态矩阵控制要求模型长度N 过大而使在线计算量很大的弊端,它将使算法更容易在线实现。本文对各种机组调节系统进行仿真,结果表明,对于混流式和轴流转浆式机组,通过反馈校正系数和控制权矩阵的正确选择,可以解决调节时间和水击压力上升的矛盾;对于贯流式机组,提出了动态矩阵PI控制方案,可以较好的解决此类机组转速难以稳定的问题。本文还对动态矩阵控制的参数选择和闭环特性进行了讨论和分析。关键词:水轮机:水轮机调节系统:预测控制:动态矩阵控制。 AbstractH ydroel ectri cgenerati ngsethast w ot ype governi ng equi pm ent.0nei sel ectro—hydraul i c governor of turbi ne w hi ch canadj ust frequency( acti ve pow er)the other i s exci tati ongovernor of generat or w hi ch canadj ust v01tage( reacti vepow er) .They w orktogetherf orm eeti ng the requi rem ent s off requency thatthe el ectri calpow ersyst embri ngs f orw ard to.The capabi l ityofel ectro—hydraul i cgovernorofturbi nef requency thati s i m portanti n the securi ty anddependabi l i ty.E1ectro——hydraul i c regul ati ng syst emof turbi ne i s a non- 1i near ti m e——vari edm i ni m umphase system .Form anyconf i nem athem ati calm odeli sverydi ffi Ctl lel ectro—hydraul i c governor of turbi oe i s PID or som e that bases onPID .A1thoughtheendi ngi s al m ost sati sf i ed w i threqui rem ents,the stabi l i ty needi m proved.Predi cti ve controli sa com put er al gori thm .Easi l Y m odel i ng andcarryi ngout onl i ne bri ngsi tto m ore and m ore appl i cati on i n i ndustry contr01.D M C i sthe predi ct i ve contr01s thatare w i del Y used.Thepaper i m proves the ari thm eti c of D M C andappl i es i t i nE1ectro- hydraul i cregul ati ng syst emofturbi ne and studi esthe v01tage anddi rectl Yaf f ectsthequal i tyofcondi t i on,set t i ngupanaccurat et.Atpresent ,t hem ai nw ayofone ofon m any t ypes turbi ne.D M C i m provedavoi dsthe abuse thatcan m ake the m odelqui cker truncated.Itl ong and Nvery bi g andquanti ty of cal cul ati on l arge.It m akes theari thm eti c easi er real i zed.D M C need m akethe m odelThe paper m akes si m ul ati on f or each t ype ofsyst emof turbi ne.The resul ts of si m ul ati on showthat f or the Franci s andKapl anturbi nes the contradi cti on betw eenregul ati onti m e andpressure i ncreasi ng canbe sol ved byl ogi calchosen off eedback adj ustm entCO St- w ei ghti ngm atri x.For tubl ar turbi ne the dynam i c m at ri x PI contr01 schem eE1ectro—hydraul i c regul ati ngcoef f i ci entand controlcanef f ecti vel Y sol ves thedi f f i cul ty of speed stabl i ng ofFi nal l Y,thi s paper di SCU SSeS and anal yzescl ose一100p characteri sti c ofthi s t ype turbi ti e.the chosen ofparam et ers anddynam i c m at ri x controI.Keyw ords:hydro—tarbi ne:hydro—turbi ne governi ng system ;predi cti ve controldynam i c m atri x contr
