【Abstract】 The solvability conditions for the LQ inverse problem of the multi-variable linear time-invariant system are studied with the polynomial matrix approach.The sufficient and neces-sary conditions for the solution of the general LQ inverse problem and the algebraic charac-terization of the solution have been obtained .更多还原
