Resumo: | This thesis presents contributions to sensorless control for permanent magnet synchronous motors. A maximum torque per ampere strategy is used to generate the current control reference in synchronous reference frame. When this type of strategy is used this gives better performance in operations up to rated speed can ve achieved. Two discrete time domain current control proposals are presented for motor applications using microcontrollers. The first technique utilizes a disturbance observer associated sliding mode controller to minimize the effect of matched and unmatched disturbances, as well as variations and uncertainties parameters. The second strategy provides new conditions of linear matrix inequalities for the digital redesign of proportional integral controllers applied to plants described by first order models affected by a sampling period delay in the implementation of digital control. The current control technique presented require the knowledge of the rotor speed/position of the motor. This information that can be obtained through mechanical sensors or rotor speed/position estimation algorithms. Due to the fact that mechanical sensors reduce the robusteness of the control system, three rotor speed estimation techniques were proposed in this work. The first strategy uses the observation of the counter electromotive force of the motor through the use of a disturbance observer, and from this information a speed adaptation law is proposed in the stationary reference frame. The second technique uses a model reference adaptive system. A linearized model is necessary for the development of this technique. In order to increase the robustness of the proposed algorithm the proportional-integral regulator used in classical methods was replaced by a sliding mode regulator. The third estimator, in the discrete time domains, uses the observation of the currents in the discrete time domain to develop a rotor speed adaptation law in the synchronous reference frame. The stability analysis and convergence of the controllers and estimators are presented. Simulation and experimental results validate the proposed algorithms. |

Para a obtenção de um desempenho eficiente na faixa de operação é utilizada a estratégia de máximo torque por ampere para geração de referências de corrente no referencial síncrono dq. Visando aplicações em microprocessadores, duas propostas de controle de corrente no domínio do tempo discreto são apresentadas. A primeira utiliza um controlador por modos deslizantes associada a um observador de distúrbio para minimização do efeito dos distúrbios conhecidos e desconhecidos da planta, bem como das variações e incertezas paramétricas. A segunda estratégia fornece novas condições de desigualdades matriciais lineares para o reprojeto digital de controladores proporcionais integrais aplicados a plantas que podem ser descritas por modelos de primeira ordem afetados por atraso de um período de amostragem. Ambas as técnicas de controle necessitam do conhecimento da velocidade/posição rotórica que podem ser obtidas através de sensores mecânicos ou de algoritmos de estimação de velocidade/posição rotórica. Três técnicas de estimação da velocidade rotórica foram propostas nesse trabalho. A primeira técnica utiliza a observação da força contra-eletromotriz do motor através da utilização de um observador de distúrbio, e a partir dessas informações uma lei de adaptação da velocidade é proposta no referencial estacionário. A segunda estratégia de estimação proposta utiliza um sistema adaptativo por modelo de referência. Para o desenvolvimento desta técnica mostra-se necessária a linearização do modelo em coordenadas síncronas. Visando aumentar a robustez do algoritmo proposto o sistema de adaptação clássico foi substituído por modos deslizantes. A terceira técnica, desenvolvida no domínio do tempo discreto, utiliza a observação das correntes estatóricas do modelo simétrico no referencial síncrono para o desenvolvimento de um lei de adaptação da velocidade no referencial síncrono dq. As análises de estabilidade e da convergência dos algoritmos são apresentadas. Resultados de simulação e experimentais validam as técnicas propostas.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESporUniversidade Federal de Santa MariaCentro de TecnologiaPrograma de Pós-Graduação em Engenharia ElétricaUFSMBrasilEngenharia ElétricaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessControle sensorlessControle de correnteEstimação de velocidade rotóricaDomínio do tempo discretoMotor síncrono de ímãs permanentesCurrent controlDiscrete-time domainPermanent magnet synchronous motorSensorless controlRotor speed observerCNPQ::ENGENHARIAS::ENGENHARIA ELETRICAContribuição ao controle sensorless de motores síncronos de ímãs permanentesContribution to the sensorless control for permanent magnet synchronous motorsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisVieira, Rodrigo Padilhahttp://lattes.cnpq.br/7274686165301866Gründling, Hilton Abíliohttp://lattes.cnpq.br/6128096609162437Gastaldini, Cristiane Caudurohttp://lattes.cnpq.br/5279383710532072Baratieri, Cassio Lucianohttp://lattes.cnpq.br/4563231120744990Fernandes, Eisenhawer de Mourahttp://lattes.cnpq.br/7934688409399283http://lattes.cnpq.br/4187997635604405Gabbi, Thieli Smidt3004000000076008772c637-1daf-4cd2-b7b2-077e9bf2f621db80f4e6-b226-41d1-8d9b-25a56885d8744188a74e-402a-499d-80e2-be75ac07774e4e112eab-d54b-4b2e-924c-f01de5731f44443d0e65-96ed-49e5-a9fc-eab1b09e26e172d0c324-d846-4487-9476-5524cf99b1bbreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALTES_PPGEE_2019_GABBI_THIELI.pdfTES_PPGEE_2019_GABBI_THIELI.pdfTese de Doutoradoapplication/pdf13107179http://repositorio.ufsm.br/bitstream/1/19496/1/TES_PPGEE_2019_GABBI_THIELI.pdfd7dd1f03cc08890f47898901f8bfaae0MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;

This thesis presents contributions to sensorless control for permanent magnet synchronous motors. A maximum torque per ampere strategy is used to generate the current control reference in synchronous reference frame.

Two discrete time domain current control proposals are presented for motor applications using microcontrollers. The first technique utilizes a disturbance observer associated sliding mode controller to minimize the effect of matched and unmatched disturbances, as well as variations and uncertainties parameters. The second strategy provides new conditions of linear matrix inequalities for the digital redesign of proportional integral controllers applied to plants described by first order models affected by a sampling period delay in the implementation of digital control. The current control technique presented require the knowledge of the rotor speed/position of the motor. This information that can be obtained through mechanical sensors or rotor speed/position estimation algorithms.
