摘要
网络诱导时延和数据包丢失、错序等问题会严重影响网络化控制系统的性能甚至使系统不稳定。对于球杆系统这样具有开环不稳定和典型的非线性特征的系统来说尤其明显。为了解决这一问题,采用网络化预测控制算法(Networked Predictive Control,NPC)来设计球杆网络化控制系统。介绍了网络化预测控制算法的设计,球杆对象的辨识建模,并通过仿真与实验结果验证了该设计的有效性。
Random time delay and packet dropout can degrade the performance of networked control systems and even cause system instability, especially for the Ball -Beam System of some natures such as instability in open -loop, and nonlinearity. To solve this problem, this paper adopts the networked predictive control （NPC） method to design the ball - beam system networked control system. The principle of NPC is described, the modeling of the ball - beam system with identification method is explained, and the simulation and experiment results are provided to verify the effectiveness of the proposed design scheme.
