【Abstract】 This paper introduces a new concept called kernel representation as well as its applications. The significance of the kernel representation is discussed in detail from the following aspects: the relationships between the kernel representation and nonlinear right coprime factorization, the background the concept put forward and its applications in Youla parameterization. Meanwhile, applications of nonlinear coprime factorizations in control systems, such as the existence of the coprime factorizations, the robust stability, the identification and the design of the observers, are discussed briefly.更多还原
