Abstract: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.

Abstract:In this paper,a test and diagnosis system based on GPIB bus is introduced.It can be used to make collective performance test of the objects to be measurand,it can also be used to make orientation of fault.Owing to its high universality and automation degree,it can be used to test,repair and diagnose instrument for the army.

Abstract:A digital microwave communication synthetical test instrument is such one which integrates more than ten instruments into one test system.It can measure most of the parameters of the digital microwave communication system.It is suitable for the measurement of the mobile digital microwave communication system especially.The principle and application of the digital microwave communication synthetic test instrument are introduced in this paper.

Abstract:The computer main board is the core of the system and is often the important measuring item.Applying the micro\|diagnosis method,the measurement of main\|board of flight parameter is realized.The covering rate of fault is high.For the popularization to be applied to the test of other airborne computer systems this method is valued.
