自适应PID在网络化控制系统中的应用

摘要

将粒子群自适应的控制模型与常规PID控制算法相结合,利用粒子群优化算法的PID对系统进行离线整定,并将其应用于网络化控制系统(NCS)改善网络诱导时延、调度等问题.结果表明,应用自适应PID控制的NCS能够有效地改善网络时延问题而且控制参数易于整定,具有较强的自适应性和优良的控制性能.%The control model of particle swarm adaptive combined with conventional PID control algorithm,which is used to offline setting.It is applied to networked control systems (NCS) and it is able to improve the network induce delay scheduling problems.The results show that the controlling parameter is easy to be set,which has nice adaptability Application of replication adaptive PID can improve the network delay problems effectively,which has strong adaptability and nice control performance.
