基于模型预测控制的网络控制系统设计

MPC-based Control Methodology in Network Control Systems

网络随机时延和数据包丢失问题,直接影响了网络控制系统的性能指标。针对上述问题,提出了一种基于模型预测控制的网络控制设计方法,根据网络数据传递次序重新设计了DMC的控制时序,使其更适用于网络环境下的实时控制。仿真结果表明了该方法的有效性。

Network random delays and data packet dropouts directly cause the degradations of networked control systems.A methodology based on model predictive control is proposed to overcome the non-deterministic delays in data communication of the network.The general algorithm of DMC is improved to make it suitable for network condition.The simulation results show the effectiveness of the real-time network control strategy.
