And, the width of the bistability region of VCSEL will become insensitive to the variety of the feedbackindex with great scan period.
过大的扫描周期将使VCSEL输出双稳区宽度对反馈率的变化不敏感。

So, smaller photoelectric feedbackindex should be chosen to control the bistability region more effectively, and the period of the time-varying injection current should be small.
因此，为了更有效地控制双稳区，应选取较小的光电反馈率，同时时变注入电流具有较高的扫描速率。

According to the related theories of LMI processing method for robust controller design, a robust output feedback controller is designed which satisfies the performance index requirements.
