It is highly desirable to develop a new generation of ACC. As the following mode is the most common working state of ACC, it becomes the focus of ACC research.

This paper has discussed two aspects concerning the following mode of vehicle ACC, one is the safe distance of the following mode, the other is the control modeling of this mode.

Generally speaking,the impact process of cross-basin water transfer on water environment can be induced as the following mode:transferring water-->changing the original hydrological conditions-->natural environment changing-->economy and society changing.

The <011] dislocations often dissociate according to the following mode:[101]→1 / 2[101] + APB + 1 / 6[211] + SISF+1 / 6[12] The 1 / 2< 112] dislocations often dissociate to form faulted dipoles bounded by 1 / 6< 1 12]partial dislocations.

Chromatographic detection of the intermediates and the products formed during the progression of NAD and ATP dephosphorylation by the most purified fraction of this enzyme was found to be consistent with the following mode of its action:

kariyai demonstrated two modes of arrestment response towards the patch (patch-searching mode and patch-edge-following mode), which were dependent on the amount of kairomone per patch.

A control scheme for mobile robot formation in the leader following mode is proposed.

When the speed difference between the leader and the follower is zero, the follower leaves the conscious braking mode to enter the following mode.

The objective of the boundary-following mode is to skirt the boundary of the obstacle, finding shortcuts where possible.

The direct force control (DFC) for CCV. Aircraft consists of following modes: direct lift, fuselage aiming> vertical translation and maneuver enhancement. These modes could be converted between each other, once the pilot pushes the selected button according to the various fighting tasks and some flight functions.

The direct force control (DFC) for CCV. Aircraft consists of following modes: direct lift, fuselage aiming> vertical translation and maneuver enhancement. These modes could be converted between each other, once the pilot pushes the selected button according to the various fighting tasks and some flight functions. Based on the implementation of digital control of each DFC mode with microprocessor, this paper presents a scheme for multimode synthesis and conversion between each other. The results of the system hybrid simulation experiment have shown that the technique of mode conversion is successful and the aircraft transient response during the operation of conversion is satisfactory. And this paper provides us with a feasible scheme for the realization of multimode DFC or the mode conversion for other flight control systems.

A terrain following scheme of optimal control using cubic spline path isdiscussed in detail in this paper.At first,the scheme of cubic spline developed by Funk[1]is analyzd.Funk's scheme can lead to a flight path which is better for assuring safety.But it is computed with algorithm of quadratic programming,in which hugememory capacity is needed,and the calculation is very complicated.Furthermore,in Funk's scheme,the constraints are satisfied only in sampling nodes wherethe terrain data are measured.A modified scheme,which may be called“templet-type cubic spline ap-proach”,is recommended by the authors.In the modified scheme,the cubic splineapproach is combined with templet approach,using boundary cubic spline curvesas templet ones.A boundary curve is a flight path which is determined by thelimits of pilot's or aircraft's tolerance.During terrain following mode,aircrafthas to make climbing or descending maneuvers.So there are two bounbary cur-ves.One of them is upper-boundary curve,which is limited by positive overloadand maximum flight path angle.The other is lower-boundary curve,which islimited by negative overload and minimum flight path angle.With the two boun-dary curves determined,the flight path can be so arranged that all contraints aresatisfied.All boundary parameters can be calculated off-line;thus on-linecalculations become very simple.Comparing the templet-type cubic spline approach with Funk's,we canfind that if the number of sampling nodes is N,the number of multiplicationis 16N~2+104N in quadratic programming algorithm using Kung-Tuker condi-tions,and 160 N+80 in the templet-type cubic spline algorithm.For example,suppose N=10,then the former is 26400,and the latter is 1680.In this example the amount of calculation in the new scheme is only about one fifteenth that ofFunk's.The memory capacity needed in it is much less than that in Funk's.Thus,the templet-type cubic spline approach can be implemented with micro-computer more easily.
