Based on the analysis of the principle of the ring laser gyro(RLG) light intensity control system and pointing to the self developed computer stabilizing frequency control system of RLG,the algorithms of FUZZY\|PID and the conventional PID are studied.A new kind of controller using fuzzy reasoning function for realizing PID parameter self\|adjustment is put forward in this paper.It is based on the conventional PID controller,adapting the fuzzy reasoning idea and according to different E and EC to accomplish the on\|line self\|adjustment of K\-p,K\-I and K\-D parameters.The simulation result shows that the dynamic and static characters all meet the normal algorithm and this algorithm is the more ideal control algorithm for realizing the laser light intensity control and then accomplishing the laser frequency control.
