摘要:
A relationship between the constant coefficients of the characteristic equation and the elements of the constant matrixAis determined. When the state-space approach is used, the use of this relationship reduces the work involved in expanding the dot (zI — A) which gives the characteristic equation of a stationary linear system. This overcomes the main drawback in applying the modified Routh criterion in the stability study of high-order linear time-invariant sampled-data systems.
