摘要
基于网络控制系统的状态空间统一模型和对网络动态延时的预测,提出了一种预测步数可变的广义预测控制算法,并基于实际对象的数学模型进行了仿真验证.结果表明,所提算法可很好地适应延时波动,且具有较好的控制效果.
Based on the unified state space model of networked control system(NCS) and the prediction of dynamic transmission delay,a new generalized predictive control(GPC) algorithm is put forward,in which the prediction steps are variable according to the prediction of transmission delay.Simulation is made with the mathematic model of actual object.And the simulation results show that the presented algorithm can adapt to the delay fluctuation very well,and has a fine control effect.
