Abstract
In this paper, It is showed that however we can mention the guaranteed gain margin of -6 to +∞ and also phase margin of -〖60〗^° to +〖60〗^° for single input systems as the well-known robustness properties of linear quadratic regulators (LQR). But determining the robustness of closed-loop system from the range of gain and phase margins is not corrected. By an example, this matter is explained.
