| Abstract: | The relative merits of the digital controller and analog controller in the design of DWDM transmitter controller are analyzed, and a new mixture controller is proposed. The core of this controller is a analog controller, which can ensure the stable state precision of the system. A digital controller is used to monitor and control the analog controller. And the control parameters of the analog controller are adjusted by the digital controller, so that to ensure the long term stability of the DWDM transmitter. Experimental research indicates that the system has a wavelength stability within 0. 005 nm, and can self-correct the system parameter excursion. |
