| Abstract: | In multi-loop networked control system(NCS), the share of communication resource and network (transmission) delay bring 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. |
