| 摘 要： | 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。

| Abstract: | For the continuous data packet losses existed in network control system,the state feedback packet losses compensatory model of networked control systems(NCS)is constructed and an algorithm based on continuous data packet losses compensatory of Kalman filter predictor is proposed.The NCS of continuous data packet losses compensatory is described as the asynchronous dynamical system with three events and the system stability is proved.Nice anti-disturbance and precise predict ability is provided by the compensator.The effectiveness of the continuous data packet losses compensatory by Kalman filter predictor is indicated by simulations. |
