Adaptation of the controller parameter is gradient descent procedure. The adaptive controller is derived from the discrete-time model of a digitally controlled speed servomechanism. Discrete-time model is obtained from the Z-transforms of the system signals and elements. Applied controller has distributed structure, i.e. integral action is placed in the direct path, while proportional action is positioned in the feedback path of the system. Thus, it provides improved system accuracy, while it maintains sufficient level of system relative stability. Due to presence of feedback in the system and controller structures, gradient of criterion function is computed through a recurrent procedure. Performance analysis of the speed servo-mechanism with the adaptive proportional and integral controller is performed in complex domain, using root locus techniques. The analysis indicates controller parameter influence on the system stability and reference tracking capability. Further, it shows that the adaptive controller yields zero steady state error and step disturbance rejection, as well as good system performance in the presence of modelling errors. Experiments, performed as reference tracking tasks, support the analysis.","PeriodicalId":369921,"journal":{"name":"2020 International Symposium on Industrial Electronics and Applications (INDEL)","volume":"170 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124740398","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}

Key to solution of the first challenge was to model only the VCO section and minimum needed IC pins so that one could execute closed-loop simulations.

An I-f Startup Method for Back-EMF based Sensorless FOC of PMSMs with Improved Stability During the Transition 一种提高过渡稳定性的基于反电动势的永磁同步电机无传感器FOC的I-f启动方法

Lu, Dong Wang","doi":"10.1109/INDEL50386.2020.9266266","DOIUrl":"https://doi.org/10.1109/INDEL50386.2020.9266266","url":null,"abstract":"The I-f control is often used as a startup method for back-EMF based sensorless field-oriented-control (FOC) of permanent magnet synchronous machines (PMSMs). In this hybrid control scheme, usually a large current magnitude is used for the I-f control to start the machine. After the machine reaches a certain speed when the position and speed estimations from the back-EMF based method are accurate enough, the control can be switched to FOC. To obtain a smooth transition, a popular method reported in the literature is reducing the current vector magnitude to move the current vector to the q-axis before the transition. However, the current reduction methods usually assume that load torque does not change during the process of reducing the current vector magnitude. In cases where the load torque changes, since the current vector magnitude cannot be increased automatically to reject the load disturbance, synchronism can be lost and the transition to FOC may fail. To achieve a smooth transition with improved stability during the transition process, this paper proposes an I-f startup method with compensation loops, which can move the current vector to the q-axis and fix it there even when load varies. Since the current vector is already on the q-axis in the I-f control mode, the switching to FOC is made very smooth. Experimental results verify the effectiveness of the proposed method.","PeriodicalId":369921,"journal":{"name":"2020 International Symposium on Industrial Electronics and Applications (INDEL)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130108339","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}
