This paper studies local elevation map building and autonomous motion planning based on feasible direction angle for unmanned ground vehicles (UGV). Founding on the configuration of sensor system mounted on unmanned ground vehicle, an algorithm of building local map based on multiple lasers is introduced, and the influence of dynamic obstacle is wiped out by combining with an algorithm of tracking...
The nonlinear large disturbance attenuation control scheme is investigated based on the backstepping method for the single-machine infinite-bus excitation system. Focus is given on the effect of the generator rotor on the output of the system by unknown external disturbances. The minimax method is used to reduce effectively the conservativeness of the disturbance treatment, which is brought by the...
Improving the detect efficiency of confocal LIF device by using auto-focusing and tracking method, based on image processing. The Laplacian sharpness-evaluation-function and three image difference methods were used to calculate relative position between lens and object in the LIF system and implement auto-focusing and tracking. The experimental results shown that Laplacian sharpness-evaluation-function...
