Abstract EN
In networked control systems with multi-step delay, long time-delay causes vacant sampling and controller design difficulty.
In order to solve the above problems, comprehensive control methods are proposed in this paper.
Time-delay compensation control and linear-quadratic-Guassian (LQG) optimal control are adopted and the systems switch different controllers between two different states.
LQG optimal controller is used with probability 1 - α in normal state, which is shown to render the systems mean square exponentially stable.
Time-delay compensation controller is used with probability α in abnormal state to compensate vacant sampling and long time-delay.
In addition, a buffer window is established at the actuator of the systems to store some history control inputs which are used to estimate the control state of present sampling period under the vacant sampling cases.
The comprehensive control methods simplify control design which is easier to be implemented in engineering.
The performance of the systems is also improved.
Simulation results verify the validity of the proposed theory.
