摘要：

A characterization of observability for linear time-varying descriptor systems E(t)x'(t) + F(t)x(t) = B(t)u(t), y(t) = C(t)x(t), is given. E is not required to have constant rank. The characterization is designed to reduce symbolic computation and has potential advantages even when E is nonsingular. It is also shown that all observable analytic descriptor systems are smoothly observable even if they are not uniformly observable. Finally, the external behavior of time-varying descriptor systems is characterized.
