Rate azimuth inertial platform/log/gravity matching is a simple passive navigation system,to improve its fault-tolerant performance,and a federated Kalman filter is designed for this integrated system.

Robust passive control for discrete time-delay system;

Delay-dependent passive control for linear systems with delay;

Robust passive control for singular systems with time-varying uncertainties;

Passivity-based control of voltage source PWM rectifiers based on Hamilton theory;

Taking phase-shifted full-bridge soft switched power supply as research object, introducing passivity-based control theory into its closed-loop control, the Euler-Lagrange average model of common Buck type DC/DC converter was established, the passivity-based control law of DC/DC converter was deduced, and the simulation result was analyzed.

On the basis of passivity-based control in general kinetic system, a Euler-Lagrange model of DC/DC Buck converter has been established, and hence its passivity-based control law is introduced.
