It first designs a referenced system according to a given performance, then takes the state of the referenced system as the dynamic equilibrium state of the original control system, designs a control law to make the system state move to its dynamic equilibrium in a scheduled way.
Regard Windows2000 as the operating platform, regard Visual C ++ as the programming environment , adopt module programming technology, is it make user interface to design , utilize trends chain storehouse realize move the directional control of the controller to PMAC.
The infrared image this paper involved is with sky-sea background conditions, and the targets are isolated bright spot with lack of structure and texture information, and the targets move slowly between the sequence images.
The masses and inertia of the open chain links after the platform are reckoned in the model, and the dynamic model of the system is established using symbolic numeric approach. Based on elastic theory and finite elements method, the kineto elastodynamic equation of the manipulator is also established by symbolic deriving. The method is coded into FORTRAN, and an example of KED analysis of Tianfu I type spot welding industrial manipulator is given as well.
On the basis of the kineto elastodynamics, the governing equation of flexible redundant manipulators is developed, which includes the coupling of rigid body and elastic motions.
The low-frequency terms in the expansion involve an independent fractional Brownian motion evaluated at discrete times or, alternatively, partial sums of a stationary fractional ARIMA time series.
There exist three kinds of equilibria that may occur in adoption of current technology, which mainly depends on the level of operating costs and the first-move advantage.
The simulation results show that the FFA snake model has a large capture range and can move a snake into the boundary concavities, and that it is able to obtain the object of interest's contour precisely.
The author starts with a standard weighted Laplace operator on a Riemannian manifold with curvature bounded from below, and then move further to the unbounded below curvature case and its infinite-dimensional settings.
Results indicate that, after atoms are emitted from an atomic oven, the longer the atoms move, the worse the distribution of the atomic beam shows, regardless the laser cooling is taken or not.
Considering the effects of bending-shearing strain and tensile-compression strain, the dynamic stress of the links and its position are derived by using the Kineto-Elastodynamics theory and the Timoshenko beam theory.
In this paper some new results concerning analysis and synthesis of time optimalcontrol systems are given. We assume that the motion of controlled object is describedby linear ordinary differential equations with variable coefficient, and the final states ofthe system form a convex region of phase space. Geometric properties of the iso-chronous region of these systems in phase space and the facts connected with these whichhavc fundamental meaning for the solution of the synthesis problem are discussed.

This paper describes a new principle of long travel feed drives, based on engineering practice and bionics. There are two motor units, each with two legs, the feeding movement is continuous despite the fact that each motor unit itself operates in a back and forth mode. This mechanism has the designed characteristics and is simple in construction. Two test rigs are described, the test results are generally analyzed.
The large drift motion of the ESG under the influence of the electric torques istreated theoretically by using the phase plane method. The distribution of the singularpoints in the phase plane determines the stability of the equilibrium positions of therotor axis in the electrodes and the geometrical characteristics of the gyro's trajectoriesadjacent to the equilibrium positions. The results obtained help to understand the driftcharacters of strapdown ESG, and to select the suitable position of the rotor ax...
