摘　　要：伺服跟踪精度是伺服跟踪系统的一个重要指标,涉及到跟踪算法和硬件系统的快速性和准确性。但由于指令系统的传输延迟,给伺服跟踪系统引入了与网络应用环境密切相关的相对误差。为此,在不改变伺服跟踪系统比例积分微分(PID)参数的前提下,采用一种位置补偿算法,根据伺服控制指令进行外推,进而补偿传输延迟造成的影响。仿真结果表明,位置补偿算法提升了伺服跟踪精度,能够满足伺服跟踪系统的使用需求。Servo tracking precision is an important index of servo tracking system,which involves the fastness and accuracy of tracking algorithm and hardware system.However,due to the transmission delay of the command system,a relative error that is closely related to the network application environment is introduced into the servo tracking system.For this reason,without changing the proportion integration differeniation(PID)parameters of the servo tracking system,a position compensation algorithm is used to extrapolate according to the servo control instructions,thereby compensating the impact of transmission delay.The simulation results show that the position compensation algorithm improves the precision of servo tracking and can meet the requirements of servo tracking system.
