摘要
选用TI公司数字信号处理器TMS320F28335作为系统控制器设计实现了一种用于航天相机成像质量检测和评价的动态目标模拟器稳速控制系统。首先,对电控系统进行了说明,介绍了动态目标模拟器的总体结构;然后,对直流电机和负载建立控制模型,分析了测速方法、测速精度和干扰因素;最后,用MATLAB/Simulink对控制系统在无干扰和有干扰两种情况分别建立了仿真模型,并进行了仿真分析,仿真结果表明两种情况下转台稳速控制精度都满足技术指标要求。
In this paper a simulation system of dynamic target for space camera was designed and realized. The DSP TMS320F28335 was chosen as the control computer. Firstly, the architecture of simulation system and control system were introduced in all. Secondly,the models of DC motor and load was introduced,and a method of speed measurement and the speed precision was analysed. Thirdly, the control system, with and without disturb, was simulated by the MATLAB and the simulation result is as well as expected.
