| Abstract: | The controller design for networked control systems(NCSs)with communication sequences is proposed.The communication sequences which make the input and output available in a time-sharing mode is proposed to reduce the effect of bandwidth constraint.Then system model of NCSs with communication sequences is built.Based on this,controller design procedure is divided into two parts:the first part is to design Kalman filter for giving optimal state estimated value,the other is to design LQG controller by consider... |
