Analytical developments show that the dynamics of the high-frequency tracking loop varies with differential inductances, which in turn depend on the machine operating point due to saturation. On-line estimation and adaptation of the small-signal gain of the loop is proposed here, allowing accurate auto-tuning of the sensorless control scheme, even without any a priori knowledge of the machine parameters. Interesting byproducts of this proposal are the possibility for on-line adaptation of the current controllers and of the injected voltage magnitude, leading to important advantages from the performance, loss and acoustic point-of-view. The theoretical basis of the method will be first introduced and the main concept demonstrated by means of simulations. Implementation has been carried out using the hardware of a standard industrial drive and two 2.2 kW prototype IPMSMs. Experimental test results demonstrate the feasibility and effectiveness of the proposal.","PeriodicalId":386486,"journal":{"name":"2017 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125129638","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 speed estimator is formed using stator flux and electromagnetic torque based model reference adaptive system, which performs better during transient conditions and reduces steady state error for wide rotor speed variations which includes low speed regions. The proposed PDF-PDF controller reduces the overshoot and improves settling time of the system. The stability of the proposed estimator is verified through small signal model and the machine parameter sensitivity is also analyzed. The performance of the proposed estimator and controller is validated by considering variation in the low speed regions which includes standstill condition. The simulations are carried out through MATLAB/Simulink and it is also experimentally verified through FPGA controller based 1.2hp laboratory prototype PMSM drive. It is found that the maximum estimated rotor speed and position error are ±2 rad/s and ±1° respectively during low speed operation at transient and steady state conditions.","PeriodicalId":386486,"journal":{"name":"2017 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127974147","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 proposed technique handles the state of the inverter as a discrete control variable in contrast to the classic vector control in which the discrete model of the inverter is not considered. An effective formulation of cost function is used, in which there is no need for tuning the value of a weighting factor that is usually used in conventional forms, and thus saving computational time. In addition, the formulation introduces a way to investigate deeply the operation base of model predictive current control procedure. A sensorless approach is used, based on an improved Luenberger observer in which stator current, rotor flux, speed and load torque are estimated. Firstly, the dynamic performance of the drive is tested by simulation using Matlab/Simulink software. The experimental validation for the new procedure is performed utilizing a dSpace1104 control prototyping board. The feasibility of the proposed control technique is realized through the obtained measurements, which prove a precise transient dynamic performance of IM drive for the given speed commands.","PeriodicalId":386486,"journal":{"name":"2017 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131624764","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 influence of magnetic saturation and temperature variation on the estimated rotor flux position are mitigated through a direct back-EMF measurement. This is accomplished by setting to zero for a short time the phase current on one of the three-phase windings, while the other is tasked to generate the whole motor torque. The proposed method does not require any motor parameter knowledge, it does not require any additional high frequency test signal and it can be exploited under standard drive operating conditions.

The paper presents the model and develops a linear and a sliding-mode observer. Estimation is based on the dynamic equation of the flux magnitude in the rotating reference frame. The stationary-frame fluxes are obtained using a voltage model observer — they are used for field orientation and also to compute the flux magnitude. Based on the measured voltages, currents, and with known flux, the paper estimates the rotor time constant inverse using a Pseudo-MRAS sliding mode observer. The paper also presents a linear observer, however, it is shown that this design does not perform. The method proposed is simple and is not highly computational.

The idea of the predictive PLL is derived from the direct-model predictive control (DMPC) principle. The predictive PLL uses a limited (discretized) number of rotor-angles for predicting/estimating the back-electromotive-force (BEMF) of the PMSG. subsequently, that predicted angle, which optimizes a pre-defined quality function, is chosen to become the best rotor-angle/position. Accordingly, the fixed gain proportional integral (FGPI) regulator that is normally used in PLLs is eliminated. The performance of the predictive PLL is validated experimentally and compared with that of the traditional one under various operating scenarios and under variations of the PMSG parameters.","PeriodicalId":386486,"journal":{"name":"2017 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"47 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114097246","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}
