Since the observer error dynamics of a hybrid-type LPM are highly nonlinear, the performance of the proposed observer is analyzed using an approximated error model. The optimal choices of the proposed observer gains are also discussed. The authors' extensive simulation study shows that the proposed observer can identify rotor position and velocity within 3% and is quite robust with respect to uncertainties in the system model, including mechanical parameters and load force.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115418017","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}

Quick active power response of 40 rad/s and voltage response of 40 rad/s are obtained in a 30 kVA test model. To realize these quick responses, a controller with multi-microprocessors is used, in which the minimum sampling time is 185 /spl mu/s. Moreover, cooperative power flow control between the rectifier and inverter is added to power, voltage and speed controls of the generator/motor. Chopper control for overvoltage suppression is added to the DC link voltage control. Continuous operation can be realized even during such electric power network faults as 1-line, 2-line and 3-line ground faults due to these controls.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115288636","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}

An optimal soft-starting is one that starts the motor with minimum voltage and reduced starting current limit (CURLIM). Starting current limit is different for motors of different ratings and for the same motor under different initial load conditions. Fuzzy logic has been adapted with a triangular membership function with a finite overlap between two membership grades to achieve the adaptive parameter setting capability. It features automatic setting of current limit and the optimality is achieved by performing the task with appropriate settings for a maximum firing angle (/spl alpha//sub max/), decrement of /spl alpha/ (/spl Delta//spl alpha/) and the delay time between the two successive decrements (/spl Delta/t) calculated based on 'fuzzy logic'. The hardware interface is developed around an '8051 microcontroller based rapid prototyping tool' which interfaces the personal computer (PC) with the external world through its serial communication link. This tool improved the ease with which a prototype algorithm could be developed. All the algorithms are tested on different motors in the laboratory under different load conditions and found to be reliable and optimal. In all, a novel fuzzy logic based soft-start scheme for AC chopper fed induction motor drive is proposed and implemented using a rapid prototyping tool.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126217848","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 control method uses an adaptive rotor flux observer and a suitable adaptation law for the speed estimation. It has been found that this method is superior to many other methods when the performance versus complexity criterion is considered. The adaptation law is obtained by a general one, valid for any induction motor parameter estimation. A comparison between the floating and the fixed point DSP implementation of the proposed method is presented. In fact, the appearance of new and powerful fixed point DSP microcontrollers makes the fixed point solution very attractive for many industrial applications, such as retrofits, conveyors control, and a lot of manufacturing process control. Different algorithm implementation issues, such as the online computation of the observer gain matrix and of the discrete motor model are discussed in this paper. Simulation and experimental results for the two cases (fixed and floating point DSP implementation) are shown.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123825275","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}

Furthermore, it is possible to reduce computation time by separating initial value variables into dominant and dependent groups from their interactive relations.

However, the more complicated the plant, the more difficult its system identification becomes. In this paper, the authors propose to identify a modified plant with a minor control loop (MCL), fedback with just an output, instead of identifying an original plant itself. As to the design of the MCL, the original plant is modified to have an optimal damping factor. To identify the modified plant, the autoregressive exogenous (ARX) model and least squares method are applied. Through this system identification, the authors can derive an exact uncertainty between the nominal and identified parameters. Therefore, a robust vibration suppression control system, which has a wide bandwidth, can be systematically designed. The effectiveness of the proposed design method for a servomotor-fed two-mass resonant system is demonstrated through simulations and experiments.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131711579","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}
