This observer estimates load torque (which is considered as disturbance) using knowledge of speed and stator currents. The speed is normally measured using speed sensors like optical encoder. In this work, speed and rotor position are estimated using sliding mode observer (SMO). This estimated speed is given as an input to NLDO. Thus these two observers are cascaded in this scheme for sensorless vector control. Advantage of proposed cascaded scheme is that it replaces three PI controllers by state feedback controller. State feedback control gain can be mathematically determined using pole placement, thus avoiding complex procedure of tuning three PI controllers.","PeriodicalId":386486,"journal":{"name":"2017 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"36 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":"123603774","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 stator flux linkage amplitude and electromagnetic torque are the two controlled variables which are regulated in stator flux frame. Unlike the two most conventional sensorless methods at low speeds, high frequency (HF) rotating carrier voltage injection into stationary reference frame and HF pulsating carrier voltage injection into estimated rotor reference frame, in this presented method, a HF flux signal is superimposed into the amplitude of the flux reference, i.e., to the stator flux reference, and then rotor position is estimated by demodulating the flux responses coming from flux observer. The advantage of the proposed method is that the HF signal is closed loop controlled thanks to the high bandwidth of the flux loop and that low pass filter (LPF) in torque and flux feedback loop is not required. Experimental results validate the feasibility of the proposed sensorless control technique and prove that the rotor position can be estimated accurately in both steady states and dynamics.","PeriodicalId":386486,"journal":{"name":"2017 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"1 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":"130814967","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 addition to typical optimization objects, such as cost, torque ripple, machine losses, power, etc., the capability to control the HS-PMSMs using self-sensing methods is considered. Instead of static magnetic anisotropies, which are commonly used for low-saturated PMSMs, dynamic magnetic anisotropies are introduced in this paper to define objectives for the SSCC (self-sensing control capability) of highly-saturated PMSMs properly. Moreover, torque ripple optimized carrier signal injection is taken into account in the stage of the machine design. One optimized design is selected from the pareto front and compared the reference design in this study. Results from the FE analysis confirm the good SSCC of the optimized design.","PeriodicalId":386486,"journal":{"name":"2017 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"1 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":"129342350","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}

Thereafter a neural network approximates the actual rotor position from the integrated currents of the idle phases.

The current ripples caused by active voltage vectors in DTC are utilized by the rotor position estimator. Then, the estimated rotor position serves as an input for a model-based stator flux estimator in order to steer the switching state generator. The proposed rotor position estimator exhibits a good accuracy without introducing additional test signals. This approach preserves many advantages of DTC in controlling electromagnetic torque and stator flux, such as the absence of a motion state sensor and pulse width modulation strategy. Furthermore, the effect of varying steady-state voltage vector on estimation of rotor position is studied. The rotor position estimation error has positive correlation with the rotational speed when the switching frequency remains constant. Simulation results verify the feasibility and effectiveness of the method in estimating the rotor position and controlling both the electromagnetic torque and the stator flux and the effects of varying steady-state voltage vector on rotor position estimation.","PeriodicalId":386486,"journal":{"name":"2017 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"13 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":"133123621","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}

Then, direct current values are applied in a fixed stator direction so that the rotor aligns in specific positions giving information on the PM flux linkage. Experimental results are provided on a PM-assisted synchronous reluctance motor prototype, confirming the validity of the proposed method.
