作者： TIAN Jian-hui, QIAN Lin-fang School of Mechanical Engineering Nanjing university of Science and Technology Nanjing, china YANG Xiao-han Military Research Department North institute of Science Technology &information Beijing, china

An intelligent sliding mode controller has been developed for the tracking control of weapon pointing systems with uncertain external disturbances and system parameters *** this control scheme, nonsingular terminal sliding mode and Radial Basis Function neural network have been merged to compensate the uncertainties automatically. The control signal, therefore, has also been soften to reduce the chattering of the control system. The effectiveness of the control scheme has been verified by a unmaned turret pointing system simulation tests. This appoach can also be utilized for the design and implementation of a lage class of modern weapon pointing and platform systems with superior performance capabilities.

In order to realizing remote control and information collection quickly and reliably, the mobile robot with remote control is designed. In the paper, according to analysis of the overall structure, hardware circuit of the robot system is designed. Because the CAN2.0 standard only makes physical layer protocol and data link layer protocol, application layer protocol is ruled according to robot control system. In the last part of this paper, the software of master/slave computer is introduced in detail. The experiment shows that running performance of robot control system is balanced、efficient and has satisfied the practical demand.

The system structure and working principle is described briefly which integrate the active front steering (AFS) system and electric power steering (EPS) system. According to the principle and the necessary simplification of the integrated system, the integrated system mathematic model was given. To study the impact of variable gear ratio (VGR) on active damping control of EPS, the matlab simulation was carried out. Simulation results show that variable gear ratio has only a minor impact on the active damping control of electric power steering system;the original active damping control can still be used normally without changes.
