针对网络控制系统中普遍存在的连续丢包问题,建立了网络控制系统状态反馈丢包补偿模型,提出了1种基于Kalman滤波的连续丢包补偿器算法。把具有数据包连续丢失补偿的网络控制系统描述为具有3个事件的异步动态系统,并且给出了系统稳定性的证明。该补偿器具有较高的预测补偿和抗干扰能力。仿真结果表明卡尔曼滤波连续丢包补偿器算法的有效性。
Aiming at the problem of continuous packet loss in networked control system, a state feedback packet loss compensation model of networked control system is established. An algorithm of continuous packet loss compensator based on Kalman filter is proposed. The networked control system with continuous lost compensation of data packets is described as an asynchronous dynamic system with three events and a proof of system stability is given. The compensator has a high prediction and compensation and anti-interference ability. The simulation results show the effectiveness of Kalman filter continuous packet loss compensation algorithm.
