摘要
在多回路网络化控制系统中,通讯资源的共享和网络传输的时延为系统分析和设计带来新的问题.运用非线性规划理论,分析和推导了多回路网络化控制系统中采样频率优化问题,并由推导过程归纳出易于计算机编程实现的工程化求解方法.通过仿真示例验证了所提出方法的有效性.
In multi-loop networked control system (NCS), the share of communication resource and network transmission delay brings up new issues on system analysis and design. With the use of nonlinear programming theory, the problem of how to determine optimal sampling frequencies for every control loop in multi-loop NCS is solved. Moreover, a method suitable for computer programming in practical engineering is also concluded. Finally, an example is presented to show the effectiveness of the method.
