Abstract

"APARELHO E MéTODO DE CONTROLE DA OPERAçãO DE COMPRESSOR LINEAR POR MEIO DE RECONHECIMENTO DE PADRãO". Em um Aparelho e um método de controle de operação de um compressor linear com um reconhecimento de padrão de operação de um compressor com eficiência ideal pelo reconhecimento de um traço sobre um gráfico sobre a relação entre corrente e deslocamento como um padrão e pela detecção da variação do padrão, o Aparelho de controle de operação do compressor linear com o reconhecimento de padrão inclui uma unidade de cálculo de deslocamento que calcula o deslocamento alimentado pela corrente detectada na unidade de detecção de corrente e pela voltagem detectada na unidade de detecção de voltagem, a unidade de reconhecimento de padrão sendo alimentada pelo deslocamento produzido pela unidade de cálculo de deslocamento e a corrente produzida pela unidade de detecção de corrente e que detecta um padrão de acordo com um traço correspondente ao deslocamento e à corrente, uma unidade de controle de curso sendo alimentada por um padrão pela unidade de reconhecimento de padrão e que dá saída a um sinal de controle de chaveamento em função do padrão alimentado, e uma unidade de circuito elétrico alimentada pelo sinal de controle de chaveamento produzido pela unidade de controle de curso e que dá saída a uma certa voltagem ao compressor linear, de acordo com o que é possível realizar um controle de TDC de um pistão, considerando um erro devido a características de falta de linearidade, melhoram a eficiência de operação de um compressor linear e têm uma região de controle ampla e precisa.
