H-inf control solves the system problems such as narrow frequency bandwidth, large phase lag, weak robustness and actuator saturation.

The optimization of power function is implemented by H∞control theory and m-synthesis toolbox in Matlab and the design o.

This paper studies the problem of designing robust H∞controllers for networked control systems (NCSs) with passive time-varying sampling period.

Based on Lyapunov stability theorem,fuzzy guaranteed cost H∞control is obtained by state feedback control.

The sigular H_∞ control on state-feedback for descriptor linear systems;

For the model, an H_∞ control strategy with output feedback from gas observers and consideration of control cost were given.

Secondly,according to disturbing restraining index,the H_∞ control strategy is presented explicitly,the nonlinear part is regarded as the perturbation of the system model,and frequency identification of the uncertainty is carried out.

In this paper,an approximate model of Buck DC/DC converter is established and a disturbance attenuation H ∞ controller is designed under the strong non-linear and load variations of the converter.

Riccati approach and LMI approach are analyzed systemically,which have been currently used in standard H ∞ control problems,while designing the robust state feedback controllers.

Then, we designed a robust controller for aircraft attitude control in the frame of nonlinear H ∞ control.
