Abstract

"CONTROLADOR DE MOTOR, SISTEMA DE DIRECIONAMENTO DE SUPORTE ELéTRICO, E, PROCESSO DE CONTROLE DE OPERAçãO DE UM MOTOR ELéTRICO". Um controlador de motor controla a operação de um motor elétrico (28). O controlador de motor inclui sensores (30, 97, 102) para perceberem pelo menos uma característica de operação dinâmica do motor e para fornecer um sinal indicativo de pelo menos uma característica de operação do motor dinâmica percebida. Um regulador de ganho variável (190) recebe um sinal de solicitação de comando de corrente possuindo um valor e fornece um sinal de controle de corrente de motor possuindo uma funcionalidade de valor relacionada ao valor do sinal de solicitação de comando de correnre recebido e um valor de controle de ganho. Um programador de ganho (196) é acoplado de forma operacional ao regulador de ganho variável (190) e ao sensor (30, 97, 102) para fornecer o valor de controle de ganho para o regulador de ganho variável (196) em resposta à pelo menos uma característica de operação do motor dinâmica percebida para dessa forma controlar a quantidade de ganho do regulador de ganho variável (190). O controlador de motor inclui adicionalmente um circuito de acionamento (204, 120) conectado de forma operacional ao regulador de ganho variável (190) e ao motor (28) para energizar o motor em resposta ao sinal de controle de corrente de motor.
