【摘要】 陀螺稳定平台常用于稳定瞄准线或者视场,广泛应用于车辆、飞机、导弹等运载体中,目的是为了消除运载体在运动过程中对视轴的影响,给观测者提供稳定的视野。论文在调查和研究了大量陀螺稳定平台相关资料的基础上,设计了一款以车辆为载体的数字式双轴陀螺稳瞄控制系统。论文首先研究了陀螺稳定平台的发展历程,对以往陀螺稳瞄系统进行比较；从理论上分析了双轴稳定平台的工作原理和优缺点,在通用双轴陀螺稳定平台的基础上添加了横滚方向陀螺输入信号,能够对俯仰和方位两个方向进行补偿。对陀螺稳定平台速度环的各个模块进行建模,并利用Matlab对系统进行仿真。然后设计了控制系统的硬件电路,硬件部分主要分为俯仰控制板和方位控制板,并且使用了TI最新推出的数字信号处理器TMS320F28335作为核心处理器,大大的提高了运算速率。重点对电源模块、数据采集模块和控制模块等电路的进行研究设计。最后对利用CCS3.3对硬件电路进行分模块调试,调试完成之后设计了整个控制系统的软件环节。通过调试和实验,本控制系统的各个模块工作正常,两个控制板之间也能正常通信,各项性能满足要求。更多还原

【Abstract】 In order to eliminate the influence on the visual axis during the movement of the carrier, and to provide a stable vision to the viewer, gyro stabilized platform is widely used in vehicles, aircraft, missile, etc. A digital dual-axis gyro stabilized sighting control system is designed which is used in vehicle after investigating a numerous data of gyro stabilized platform.Through researching the development of gyro stabilized platform and comparing the general stable platform system. Then the working priciple of the dual-axis stabilized platform is analyzed, merits and demerits of the dual-axis stabilized platform are listed. A roll gyro input singnal is added into the system on the basis of the universal dual-axis gyro stabilized platform by which the deviation on both directions of pitch and horizon can be compensated. Each module of speed loop is modeled.then the control system is simulated by Matlab.In the hardware part, the pitching and horizontal control board circuit are designed. Operation rate is greatly improved as the TI"s latest digital signal precessor TMS320F28335is used as the core processor. Modules of power, data aquisition and control system are the key research.At last, the hardware is debuged part by part by means of CCS3.3and the software is designed.According to the debugging result, the control system works well, and the two control boards communicate properly, all the performance meet the requirements.更多还原
