Abstract:
1. A fuzzy control method for a signal receiving part in a high speed wavelength division multiplexing system, comprising following steps: A. obtaining related information of each device in a receiving system and working environment parameter information of the receiving system; B. according to the related information of each device and the working environment parameter information, finding out fuzzy control parameters which best match the related information of each device and the working environment parameter information from a fuzzy control parameter table stored in the system, and controlling the parameters of each device in the receiving system according to the found fuzzy control parameters; wherein, the step B specifically comprises: B1. searching the fuzzy control parameter table to check whether the fuzzy control parameter table comprises the fuzzy control parameters which best match the related information of each device and the working environment parameter information, if yes, issuing one group of the control parameters in the fuzzy control parameters matching condition to each device and performing step B2; or else, performing step B3; B2. judging whether quality of signals received by the system is acceptable, if yes, storing the fuzzy control parameters corresponding to configured parameters of each device and environment information, ending flow; or else, selecting another group of parameters of the fuzzy control parameters matching condition to issue to each device and returning to step B2 to judge continuously, and performing step B3 when the quality of the signals received by the system is still unacceptable after all groups of control parameters of the fuzzy control parameters matching condition have been issued to each device; B3. using a trial and error algorithm to configure different parameters and judging whether the quality of the signals received by the system is acceptable, if yes, storing the fuzzy control parameters corresponding to the currently configured parameters of each device and the environment information; or else, ending flow.
