【Abstract】 As everyone knows, the calculative amount of judging the controllability and the observability of state for the linear invariant system with multiinput and multioutput by traditional algebraic criteria increases very rapidly as the dimensions of its input,output and state Vectors do. In this paper,in view of this situation being time-consuming and needing great effort,some improved algebraic criteria of state controllability and observability for linear invariant system are established.更多还原
