At present, sensorless becomes a research hit for its lower cost and smaller size, among the present sensorless methods, Luenberger Observer has outstanding advantages for its dynamic performance, parameter robustness and high system stability. In this paper, the model of Luenberger Observer which is based on the state equation of permanent magnet synchronous motor (PMSM), and the changes of residence and induce which may lead to the error of the system are also analysed, in order to increase the accuracy of the system, current compensator is also added. In addition, 2 conditions which PMSM runs at low speed and high speed are analysed under the MATLAB model, the results show that the Luenberger Observer has better performance at high speed, but the noisy data of the useful signal is more at low speed.

An electric vehicle (EV) usually has two main power converters, namely one for the motor drive system and another for the battery-charging system. Considering the similarities between both converters, a new unified power converter for motor drive and battery charging of EVs is propounded in this paper. By using a single unified power converter, the cost, volume, and weight of the power electronics are reduced, thus also making possible a reduction in the final price of the EV. Moreover, the proposed unified power converter has the capability of bidirectional power flow. During operation in traction mode, the unified power converter controls motor driving and regenerative braking. Additionally, during operation in battery-charging mode, with the EV plugged into the electrical power grid, the unified power converter controls the power flow for slow or fast battery charging (grid-to-vehicle (G2V) mode), or for discharging of the batteries (vehicle-to-grid (V2G) mode). Specifically, this paper presents computer simulations and experimental validations for operation in both motor-driving and slow battery-charging mode (in G2V and V2G modes). It is demonstrated that the field-oriented control used in the traction system presents good performance for different values of mechanical load and that the battery-charging system operates with high levels of power quality, both in G2V and in V2G mode.

“…In typical realization, the correction is based on error between measured and calculated currents value. Assuming that derivative of disturbances is equal zero, one can write the observer equations as (14)(15)(16)(17). Located in the observer's equations (16) (17) and then (23) (24) the correction components, cause that observer calculates the proper value although estimated EMF initial values are equal to zero.…”

“…The actual investigations are mainly focused on: zero speed range [1][2][3][4], high dynamic performance [5,6], motor supplied through choke or LC filter [7][8][9] and supplied by matrix converter [1,10]. Various approaches to the sensorless control are applied: using signal injections (typical application is zero speed range), based on back EMF estimation -including continuous observer of the kind which is presented in the paper and sliding mode based observers [11], based on Kalman filter [12,13], an adaptive interconnected observer [14] and the use of the artificial neural networks [15,16]. An additional modification that improves the sensorless performance, may be the motor parameter online identification [17] which may improve sensorless performance for low speed range.…”

Original scientific paperThe paper presents results of studies on the position estimation for the permanent magnet synchronous motor (PMSM) drive using gain scheduling technique for tuning the observer's parameters. It allows a good estimation accuracy in wide range of working point change. Such observer with multi integral correction function improves the performance, but need to modify its parameters according to its speed and load.Novelty is the use of a two-dimensional gain scheduling technique and the use in the sensorless drive, where traditional solution is simple one-input scheduling variable -mainly on drives with position sensors. The look-up table output is processed using bilinear interpolation. Position observer is based on back EMF estimation. It uses predefined reference matrices of parameters, which are interpolated and depend on drive's operating point.Key words: Observers, PMSM, Scheduling, Sensorless control, Variable speed drives Unaprijeđena metoda estimacije položaja zasnovana na upotrebi dvodimenzionalnog polja za ažuriranje parametara. U radu su predstavljeni rezultati studija vezanih za estimaciju položaja sinkronog motora s permanentnim magnetima (PMSM) uz korištenje regulatora s podesivim pojačanjem za adaptaciju parametara estimatora. Metoda pokazuje dobru točnost estimacije u širokom rasponu radnog područja. Ovakav estimator s više integracijskih korekcijskih funkcija poboljšava performanse, ali i zahtijeva adaptaciju parametara ovisno o brzini i teretu.Novost predstavlja korištenje dvodimenzionalnog podešavanja pojačanja regulatora te primjena u bezsenzorskom upravljanju elektromotornim pogonom, gdje se tradicionalno koristi jednostavno ažuriranje jedne varijable -prije svega kod elektromotornih pogona sa senzorom za poziciju. Pregledna tablica izlaza koristi se uz bilinearnu interpolaciju. Estimator položaja zasnovan je na estimaciji protuelektromotorne sile. Estimator koristi unaprijed određene referentne matrice parametara koje se interpoliraju te ovise o radnoj točki.Ključne riječi: Estimatori, PMSM, ažuriranje parametara, bezsenzorsko upravljanje, elektromotorni pogon promjenjive brzine INTRODUCTIONThe Permanent Magnet Synchronous Motor (PMSM) is very often used type of motor in industrial applications. Its the most significant advantages are high power density, high torque-to-inertia ratio and small torque ripples. Such drive gives possibility to precise speed and position control at low speed range, a torque control at zero speed and has compact size. A typical control structure of PMSM drive bases on vector control method. It allows to get a good dynamics, effective performance especially during transient processes and prevents overload of the motor by controlling the torque. However, a motor shaft position sensor is required to enable the effective control of the drive. Reliable operation without sensor is still a subject of investigations. The actual investigations are mainly focused on: zero speed range [1][2][3][4], high dynamic performance [5,6], motor supplied through ...
