Neste trabalho é feita a fundamentação para os conceitos de sinais e sistemas intervalares complexos, fazendo-se o uso da aritmética complexa retangular e do conceito de intervalo de números complexos feito com auxílio da chamada ordem de Kulisch-Miranker para complexos. É apresentado também o conceito de representação intervalar e é definida a representação canônica intervalar (CIR) de funções complexas. A partir de um sistema complexo $f$, usando a função CIR, encontra-se um sistema intervalar $F$ o qual preserva, no ambiente intervalar, as propriedades de $f$, tais como estabilidade, invariância no tempo, aditividadade, homogeinidade e linearidade.References
