For multiple inputs and multiple outputs networked control systems(NCSs)with limited communication channels,the effects of system resource constraints on the performance of LQG optimal control is studied.

Based on Linear Quadratic Gaussian(LQG) theory,a LQG optimal guidance law with time-variable effective navigation ratio is studied.

LQG control problem of adjacent buildings considering local site effect;

Closed form solution of LQG control problem for seismic response of adjacent buildings;

Ship pitching stabilization of slanting rudder based on LQG control method;

The simulation results demonstrated that the active suspension with a LQG controller could improve automobile riding comfort performance enormously.

On time-domain and frequency-domain aspects,steady and transient performances of the control system were considered to designing the LQG controller.

An integrated optimization method for active suspension is presented in this paper, which takes the structure parameters of active suspension and LQG controller as optimization object and takes the weighted sum of the vertical acceleration of body, the dynamic displacements of suspension and tyre and the active control force as optimization performance indicators.

The compensatory controller was simulated and the results show that torque undulation and noise of measurement are inhibited well,the system possesses good robustness with the LQG/LTR controller.
