In this paper,the flight states estimate project of the missile active phase based on moving-base gravity gradiometer is put forward.

Using the flight survey data of the tail blade, the statistical treatment, the assumption test and the regression analysis have been made to every measured state of 183 flight conditions, by example of the helicopter tail blade, then the distribution types and the damage of different conditions are determined.

Operation estimation of the uasb reactor based on a fuzy comprehensive evaluation model;

The problem of state estimation for systems with uncertainties of unknown bound can be treated as determinant systems via ascribing uncertainty to disturbance.

Research and analysis on algorithm of state estimation of AC/DC systems;

Fast decoupling method for state estimation with PMU measurements;

A new algorithm for the distributed state estimation of power systems;

Based on KCL this article puts forward a new solution for measurement processing in state estimate,bad data check and identification and auxiliary bus replacement of electric power systems.

The equations of probabilistic state estimate algorithm are ascertained based on the weighted least squares state estimate algorithm.

Simulations also show that the method is applicable to a number of engineering problems for state estimate and parameter identification.

The simulation results indicates that this method can not only solve the combination explosion problem of calculation caused by traditional method, but also get more accuracy and creditability in maneuver target status estimation.

As a result the discrimination between the fusion track and the real track becomes smaller and the status estimation of the target gets more accurate.

Considering meshed network of distribution feed lines and node zero injection,we put forward a algorithm of status estimation based on branch currents.
