1 2th WSEAS Intenational Confeence on SYSEMS, Healion, Geece, July 22-24, 28 Feedbac Signal Etimation of an Induction Machine Dive CONSANIN APOSOAIA, ZOAN SZEKEY, and DONAD GRAY Electical and Compute Engineeing Depatment Pudue Univeity Calumet th Steet, Hammond, IN 46323, USA Abtact: - hi pape peent the tudy of flux, toque and peed etimation of an induction machine dive. he d-q model of the induction machine i ued to detemine the vaiou matice of the tate pace epeentation of the ytem. he modeling and imulation i caied out by uing the MAAB/Simulin oftwae. wo etimato uing the machine voltage and cuent meauement ae analyzed. Fit etimato i deived by diect ynthei fom tate equation, and then an optimal extended Kalman filte (EKF) i invetigated. he pefomance of both etimato ae peented and good eult wee obtained fo EKF even in the peence of the ytem and meauement noie. Key-Wod: - induction moto, feedbac ignal etimation, Kalman filte Intoduction he feedbac ignal etimation technique popoed in the liteatue fo induction machine dive ae abundant. A few elected method ae mainly baed on the following []: lip calculation, diect ynthei fom machine tate equation, model efeencing adaptive ytem, uenbege obeve, Kalman filte, lot hamonic, and injection of auxiliay ignal. Deciption and hitoical eview of thee method [2] ae beyond the goal of thi pape. he apid development of DSP baed ytem and the deceaing cot of powe electonic ha allowed the complex model and contol algoithm of induction machine to become popula fo a lage ange of application uing eithe the moto o the geneato egime of the machine [3]. In thi pape, the model of the induction machine, baed on fluxe a tate vaiable, i ued to deign and tudy two diffeent etimato that can povide the coect feedbac ignal fo an induction machine contol ytem. 2 Etimato U-I Model he goal i to deign an etimato that can be ued by a enole ac dive in ode to avoid the need of the peed meauement. A deign containt i the accuacy o that the dive mut achieve a coect etimation of the feedbac ignal equied by any cloed loop motion contol ytem. In ode to integate thi etimato model in the contol ytem of an induction machine, the tato voltage and cuent ae conideed hee a input, and the etimated output ae the magnitude and the angle of the oto flux and the electomagnetic toque. hi etimato i deived by diect ynthei fom the machine tate equation which ae witten in tem of the d-q axi component of the tato and oto flux a tate vaiable. hi choice i jutified by the fact that the ytem matix i imple than the d-q axi cuent tate pace model [3]. he machine equation ae deived fom it geneal model whee the peed of the otational d-q ytem of axe =, ince a fixed efeence fame (α-β) i conideed in thi pape. he oto voltage u d = u q = due to a quiel-cage type of oto conideed hee. he ymbol ued in thi pape ae explained in the it of Symbol in the Appendix. In matix fomulation, the machine tate pace model i [4] dx dt = A x B u, (tate equation), and y = C x (output).
