摘要
针对同时存在时延和丢包的网络控制系统建立增广模型,设计预估器估计出存在时延和丢包情况下相应的状态与控制量,对时延和丢包现象进行实时补偿。最后以Truetime为仿真平台建立仿真模型,并与采用上一时刻数据代替丢失数据的补偿方法相比较,从而表明本文的预估器补偿方法能够更有效地改善系统控制效果。
In this paper an augmented model for networked control system （NCS） with time-delay and data packet dropout was presented, and adaptive predictor was designed to estimate the corresponding state and control variables which can compensate the time-delay and data packet dropout. Then emulation model was established on the platform of Truetime. And the simulation results showed that the method proposed is effective.
