摘要
本文针对一类网络伺服控制系统中存在的丢包问题进行了研究。对于网络伺服系统中控制器和执行器之间网络存在数据丢包的情况,提出了一类新的丢包网络伺服系统模型。在此模型下,对预测函数控制算法进行分析,设计了预测函数控制产生器和数据包预测补偿器,并研究了相应的补偿策略。对某网络伺服系统的仿真实验表明了本文算法的合理性和有效性。
The packet losses problem of networked servo systems is investigated in this paper. Owing to the packet losses occur between controller and actuator in networked servo system, a new lossy packet networked servo system model is proposed. Under this model, based on predictive functional control arithmetic, predictive functional controller and packet predictive compensator are designed. The corresponding compensation strategy is researched. The simulation results about server systems illustrate that the proposed scheme is effective.
