摘要
研究了广泛用于空间激光通信、自适应光学、目标捕获跟踪等领域的压电倾斜镜光束跟踪控制技术。考虑到压电倾斜镜光束控制系统易出现跟踪精度不高、闭环带宽有限,甚至不稳定等问题,亟需对控制系统跟踪精度和动态响应性能等方面进一步研究和探索。首先介绍了国内、外压电倾斜镜的研制及其控制系统的构成,然后综合讨论了迟滞、谐振、其他干扰等限制压电倾斜镜跟踪性能提高的关键因素,并对各种方法进行了分析和比较。研究表明,目前多数研究结果只实现了部分性能的提高,缺乏对存在问题的系统性研究,尚难以在较宽的频带内实现压电倾斜镜(PFSM)高精度稳定控制。该文指出,采用系统化建模和现代智能控制算法是进一步提高压电倾斜镜控制系统综合性能的发展方向。
This paper explored the beam tracking control technology of piezoelectric fast steering mirror（PFSM）which is widely used in the application of free space laser communication,adaptive optics,target acquisition and tracking and so on.With the problems of low tracking precision,low closed loop bandwidth,and potential instability,it is urgent to investigate the tracking precision and dynamic response performance of the steering mirror control system.Firstly,the development of piezoelectric fast steering mirror at home and abroad and the structure of the steering mirror control system are introduced.Then,the key factors of hysteresis,resonance and all disturbances are discussed comprehensively which limit the improvement of the system tracking performance.And the corresponding experimental results are analyzed and compared.It summarized that the high precision and stability control of PFSM over broadband frequencies is still a challenge,as most of the current research only focused on part of performance indexes and lack systematicness.Finally,it was pointed out that using the systematic modeling method and modern intelligent control algorithm is the future development direction to further improve the control system performance.
