In this paper,first based on the inverse LQG method,a stabilizability condition via static output feedback for linear time-invariant systems is gained,then a necessary and sufficient stabilizability condition and the design method for fixed-order output feedback are derived.

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.

Combined with Jitterbug toolbox,network control models of three pendulums are simulated by using LQG algorithm.
