By calculating the circuit integral along the borders of effective damage areas, the precision measure of damage area was firstly derived in the procedure of effectiveness evaluation of cargo projectile.

To calculate effective damage area,the overlapped area of a given circle and a given arbitrary polygon is derived from the circuit integral calculation around this region.

To calculate the effective damage area,the overlapped area of the jointly covered region of multi-missiles and the given arbitrary polygon is derived from the circuit integral calculation around this region.

The result shows that the Birkhoffian system has generalized energy integrals and cyclic integrals.

Routh and Chaplygin equations for variable mass nonlinear nonholonomic system in noninertial reference frame are extended,and the cyclic integral and its condition of existence for the system are given.

In this paper, the D Alembert-Lagrange principle and the generalized chaplygin s equation for variable mass weakly nonholonomio systems moving relative to noninertial reference frame are established at first, and then the generalized energy integral and the generalized cyclic integral of the dynamical equations in the case of one-order approximation for the systems above are studied and presented.

A multi-step predictive and multi-step control algorithm of single-variable systems with integrating link;

The influence of integral element in regulator is analyzed in detail and verified by simulink.

But because the standard controller will arouse larger state-errors,an integrator is introduced to improve standard fuzzy controller.
