The algorithm introduced here is based on the modified multiple model and exploits a soft gating of the measurements to reduce the computational requirements of the approach. The position part is based on an x and y histograms scan matching procedure, where x and y histograms are extracted directly from local occupancy grid maps using probability scalar transformation. The orientation part is based on the proposed obstacle vector transformation combined with polar histograms. Proposed algorithms are tested using a Pioneer 2DX mobile robot.","PeriodicalId":401288,"journal":{"name":"2006 12th International Power Electronics and Motion Control Conference","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129890253","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}

With measurements obtained from only current and voltage sensors, the proposed estimator can capture the rotor temperature in an online fashion. First the rotor speed is extracted from the current harmonic spectrum based on the estimated rotor slot and eccentricity harmonic frequencies. Then the inductances are estimated from the induction machine equivalent circuit. The stator winding resistance at ambient temperature is the only motor parameter needed at this stage. Once the inductances are obtained, they are fed into the rotor resistance estimation algorithm to yield an estimate of the rotor resistance. Finally the rotor temperature is calculated from the linear relationship between temperature and rotor resistance. Experimental results from different motors are shown to validate the proposed scheme. The whole scheme is accurate and reliable and is therefore suitable to be implemented in a rotor thermal protection relay or a motor drive employing vector control scheme to compensate for the detuning effects","PeriodicalId":401288,"journal":{"name":"2006 12th International Power Electronics and Motion Control Conference","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121617883","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 analysis, based on the equations of the system, is made for the self commutated synchronous motor (SCSM), called also as the load commutated inverter fed synchronous motor (LCI-SM). First, the requirements of suitable acceleration of the drive and ratio of current increase during the dynamical state are transposed to the adequate commutation and control reserves of the converters. Then the influence of the reserves, kept in the steady state, on torque versus current characteristic, maximum available torque (overload capacity), selection of current limitation, power factor, loss and efficiency of the drive is analyzed. The obtained dependencies are illustrated in figures and with use of a number data. In the paper the deterioration of the steady state properties with increase of dynamics of the drive is concluded","PeriodicalId":401288,"journal":{"name":"2006 12th International Power Electronics and Motion Control Conference","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121122970","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 converter compensates the current harmonics, the reactive power and the load unbalances at its AC side and dissipates the active power excess through the chopper at its DC side.

By controlling the duty cycle, the Z-source can provide buck-boost function, produce greater or less voltage than the line voltage.
