Opis:: The paper discusses problems connected with the parameters selection of the proportional-integral observer, designed for reconstruction of magnetic fluxes and angular speed of an induction motor. The selection is performed in several stages that are focused on different criteria. The first stage consists in selecting observer’s gains and provides desired dynamical properties, taking into consideration immunity to disturbances and parameter variations of observed system. The second stage prevents an observer from DC-offset cumulation and instability. The last stage consists in setting the parameters of a speed adaptation mechanism. The impact of different settings on the properties of an observer is illustrated with experimental results, obtained in the multiscalar control system of an induction motor.

Opis:: The paper recapitulates recently conducted investigations of non-proportional Luenberger observers, applied to reconstruction of state variables of induction motors. Three structures of non-proportional observers are analyzed, a proportional-integral observer, modified integral observer and observer with integrators. Criteria for gain selection of the observer are described, classical ones based on poles, as well as additional, increasing observer’s robustness. Fulfilment of the presented criteria can be ensured with the three proposed methods for gain selection, two analytical, based on dyadic transformation and one based on optimization.

Opis:: The paper presents the principle of operation and block diagrams of different, modified MRAS-type estimators of the induction motor rotational speed. A Luenberger observer with additional integrators is used for reconstruction of magnetic fluxes in the adaptive model of the considered estimators. In the presented estimators the measurable currents of the stator winding are applied to generation of a speed tuning signal. For stator winding current reconstruction in the adaptive model there are used the Luenberger observer output signals. Moreover, in the paper there are presented the results of simulations and laboratory investigations of the described estimators operating in a multiscalar control system. For comparison, the results of similar investigations performed for a MRAS-type estimator designed basing on the so-called current model of magnetic flux estimator are given as well.

Opis:: In the paper there are presented some problems connected with reconstruction of induction motor state variables with use of a proportional observer with additional integrators. The considered Luenberger observer with additional integrators has high resistance to disturbances overlapping its input signals. In the paper the mathematical model and error equation of the observer are given. There is also described the application of the considered observer as an adaptive model in the structure of a MRAS-type estimator for reconstruction of rotational speed and magnetic fluxes of an induction motor. The quality of the observer operation is evaluated based on the quality of operation of a multiscalar control system using the values reconstructed by the observer as feedback signals.

Tytuł:: PI observer stability and application in an induction motor control system

Tematy:: luenberger observer

Opis:: The paper discusses the problem of stability of a proportional-integral Luenberger observer, designated for the state variables reconstruction of a linear, time-invariant dynamical system. It is proven, that there exists such a class of observed systems, for which the observer is always unstable, independently of its gains. Stability can be provided in every possible case after application of proposed modifications to the structure of the observer. It is proven, that stability of the modified observer depends only on its gains. It is shown, that an induction motor is the exemplary observed system, for which application of the unmodified observer is impossible due to its lack of stability, while the modified observer provides proper operation of the control system. Finally, some experimental results are presented, obtained in the multiscalar control system of the induction motor, equipped with the modified proportional-integral observer.
