【报告内容简介】

We briefly introduce the weak observability inequality. We then show several applications of this inequality: First, we obtain the equivalence between the solvability of the LQ problem and the stabilizability when the control operator is unbounded but admissible. This improves the usual definition of the stabilizability (for unbounded cases). Second, we design a kind of feedback laws via Gramian operator method. Third, we clarify the relationship between several types of feedbcak stabiliztions.
