摘要 当前通过通信网络运行的触觉（力反馈）远程呈现系统，例如互联网，需要高数据包速率来传输命令和传感器信号。提出了一种通过死区控制来减少网络流量的新方法。仅当采样信号的变化超过给定阈值时才发送数据包。引入基于无源的重建方法来重建接收器处的未传输值，保证整个系统的稳定性。实验表明，在不影响透明度的情况下，数据包速率降低了高达 87%。
Abstract Current haptic (force feedback) telepresence systems operated over a communication network as, e.g. the Internet, require high packet rates for the transmission of the command and sensor signals. A novel approach to reduce the network traffic by means of deadband control is proposed. Data packets are only sent if the sampled signal changes more than a given threshold value. Passivity based reconstruction methods are introduced to reconstruct the untransmitted values at the receiver guaranteeing stability of the overall system. Experiments show that a packet rate reduction of up to 87% is achieved without impairing transparency.
