Abstract :
In order to resolve the identification problem of the airborne Opto-Electronic stabilizing platform servo system, the detailed discussion and research are made. An identification method based on the ADALINE self-adapting neurons is presented as far as the time domain is concerned and the detailed discussion of the structural design, training design and generalization capability of the neural network is made. A method of obtaining the opened-loop frequency characteristics of the system according to the closed-loop frequency characteristic measuring data as far as the frequency domain is concerned, which resolves the difficulty of some servo systems in directly measuring the opened-loop frequency characteristics.The experimental results prove that the methods used in the paper can still effectively identify the model of the system in the big noises, with the high practical engineering values.
