步进电动机的角位移量与输入脉冲数严格成正比,电动机转动一圈后,没有累积误差,所以步进电动机是数字控制系统常用的执行电动机,并且广泛的应用在小卫星上。为了
使步进电动机在小卫星上安全运行必需在地面做相应的检测。下面介绍在小卫星有效载荷地面检测仪中利用WindowsXP多媒体定时器实现步进电动机高精度控制的方法。-stepper motor angular displacement volume and input pulses strictly proportional to motor ro

以监控和控制为目的的算法因为其数据要在数据中心汇总和处理,大多使用集中式算法,其精度较高,但通信量大。分布式算法是传感器节点在采集周围节点的信息后,在其自身的后台执行定位算法,该方法可以降低网络通信量,但目前节点的能量,计算能力及存储能力有限,复杂的算法难以在实际平台中实现-To monitor and control algorithms for the purpose because of its data to be aggregated and processed in the data
