Abstract

a presente invenção provê um método para operar um controlador duplo, o qual determina se um erro ocorre em um controlador duplo ao monitorar o estado do controlador duplo e possibilita que o controlador duplo seja operado normalmente. o método para operar o controlador duplo, de acordo com a presente invenção, calcula variações de valores de conversão dq ao executar a conversão dq de valores de saída de comando de controle de primeiro e segundo controladores, e calcula variações médias dos valores de conversão dq ao executar a conversão dq de valores de entrada de resposta do primeiro e segundo controladores. quando as variações médias dos valores de conversão dq para os valores de saída de comando de controle são respectivamente os mesmos que as variações médias dos valores de conversão dq para os valores de entrada de resposta, é determinado que o controlador correspondente está em um estado normal, com relação ao primeiro e ao segundo controladores, e quando as variações médias dos valores de conversão dq para os valores de saída de comando de controle são respectivamente diferentes das variações médias dos valores de conversão dq para os valores de entrada de resposta, é determinado que o controlador correspondente está em um estado errôneo com relação ao primeiro e ao segundo controladores. de acordo com os resultados determinados, o controlador em um estado errôneo é ajustado para um estado de espera e o controlador de um estado normal é ajustado para um estado ativo.
