摘要
弹道跟踪转镜已经成为一种跟踪拍摄弹丸飞行姿态的成熟可靠的方法。其中,伺服运动控制器是跟踪转镜的核心部件,其精度和实时性是决定系统整体性能的关键。基于advancedRISC machine(ARM)系统原理,提出了一种转镜伺服控制系统的设计方案,详细介绍了控制器的原理以及软硬件设计方案。分析结果表明:设计可以实现0.4°的控制精度,同时,部件的控制实时响应时间最小可到1ms。
Trajectory tracking rotating mirror has become a mature and reliable method to acquire the image of a flight projectile. Servo motion controller is the core component of the tracking rotating mirror, and the overall system performance is determined by the accuracy and real-time. The paper proposed a design scheme of a servo control system of tracking rotating mirror based on the ARM system principles. We give the detailed introduction of the controller principles, hardware and software design. The results show that the system achieves the control accuracy of 0.4° and the control response time of lms minimum.
