具有泵浦噪声之光动力学系统自适应控制

^Adaptive Control of Optical Dynamic Systems with Noisy Pump

以控制具有泵浦噪声的布拉格声光系统为例，研究了利用光动力学系统自适应参考模型控制技术用于控制具有泵浦噪声之光动力学系统的可行性。研究发现，由于此自适应控制技术以受控光动力学系统与其无泵浦噪声参考模型之输出差值作为反馈宗量，进而对光动力学系统之控制参数进行调整，故该技术在泵浦噪声出现时仍可消除光动力学系统控制参数的确定性扰动，因而特别适合于需要光动力学系统之运转稳定在某一具体动力学状态及按预定顺序进行转换情形下的控制。

A suggestion of using the adaptive control algorithm,which is designed originally to control the optical dynamic system with no noise-corrupted control parameter,to control the optical dynamic system with noisy pump is raised in this paper. The feasibility of this suggestion is demonstrated with the computer simulation of controlling the Bragg diffraction acoustooptic bistable system (BDAOBS) running with stochastic pump noise, where a BDAOBSwith no noisy pump is employed as the self-referenced dynamic model for control. It is foundthat,because the difference between the outputs of the noise-corrupted optical dynamic system and the self-feferenccd model is chosen to be the augument of the control function,theadaptive control algorithm is still able to be utilized in controlling the noise-corrupted opticaldynamic system.
