The filter is designed starting from a discrete time model obtained by means of a first order discretization of the original nonlinear model of the induction motor (IM). In order to obtain accurate estimation of the above mentioned variables, the load torque is included into the state variables and then estimated, thus constructing a sixth order EKF. Experimental results are shown with reference to a closed loop sensorless control system, consisting of a 750 W induction motor supplied by a voltage source inverter, a cascade controller consisting of four PI control loops and the designed EKF which gives the feedback variables. Comparison with a fifth order EKF, which does not include mechanical equation in the model, is carried out by means of simulation in Matlab/Simulink environment.","PeriodicalId":136017,"journal":{"name":"2010 First Symposium on Sensorless Control for Electrical Drives","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116575928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These types of machines typically have small inherent saliencies resulting in a low signal to noise ratio when measuring the rotor position using injected high frequency test signals. It is therefore necessary to avoid any interference between the current controller and the injected signal to achieve the highest possible performance under sensorless control. This paper proposes a novel method for integrating an alternating carrier injection scheme into a current control loop without requiring the commonly used band-pass filter. It uses a strictly synchronous injection and demodulation approach. This allows the high frequency components of the stator current to become completely invisible to the current controller and additionally to eliminate the dead time in the current control loop. Furthermore the demodulated alternating carrier will be unaffected by the fundamental component even during transient conditions. Moreover the proposed decoupling method does not require any motor parameter adjustment.","PeriodicalId":136017,"journal":{"name":"2010 First Symposium on Sensorless Control for Electrical Drives","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114878456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The voltage source inverter (VSI) is represented as event driven system with 23 modes of operation. The switching among these modes is governed by the supervisory control approach. The salient future of the switching control is system order reduction, decoupling in the design procedure, insensitivity in plant parameter changes and disturbance rejection. Simple implementation makes concept of switching control very attractive in power electronic and electrical drives. The high performance hybrid control algorithm designed by proposed approach can be easily implemented on modern FPGA platforms.","PeriodicalId":136017,"journal":{"name":"2010 First Symposium on Sensorless Control for Electrical Drives","volume":"215 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124224294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In flux weakening techniques needed to applications requiring constant torque and power operation, the produced torque is depended on the negative d-axis stator current applied to waken the magnetic flux of the permanent magnets. The proposed method uses a simple torque decoupling technique to regulate the q-axis reference current embeded into the speed controller. A flux weakening controller (FWC) is used to adjust the d-axis stator current based on the q-axis reference voltage. The performance of the overall control system is examined using Matlab/Simulink facility. Simulation results demonstrate the effectiveness of the proposed flux weakening control method.","PeriodicalId":136017,"journal":{"name":"2010 First Symposium on Sensorless Control for Electrical Drives","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133823275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pulsed test voltages are used that don't interfere with the current samples taken to control the phase currents. For this purpose, an asymmetric pulse-width modulator is applied. As a result of this strategy, the controller output influences the test voltages and consequently the current response from which the rotor position is estimated. Therefore, in this paper, a first strategy is studied in which the applied test voltages are computed taking into account the controller output. A second method is discussed as well in which the controller output is slightly delayed so that this output has no influence on the test signals. Despite the disadvantage of a small time delay, compared to the first method, no additional calculations are required to compute the test voltages.","PeriodicalId":136017,"journal":{"name":"2010 First Symposium on Sensorless Control for Electrical Drives","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128157870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High torque dynamics and robust behaviour against input voltage disturbance are achieved in the whole operation range including field-weakening. After careful correction of inverter-voltage errors and dc portions in the stator fluxes and currents not necessary for the actual operation point the difference of the stator-current space vectors in the machine and in the controlled model is employed for speed and stator resistance estimation, allowing to dispense with speed sensors. A special flux management allows infinitely slow change between driving and braking.","PeriodicalId":136017,"journal":{"name":"2010 First Symposium on Sensorless Control for Electrical Drives","volume":"81 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114328273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
