In this paper, we study a general array model of coupled reaction-diffusion neural networks (NNs) with adaptive coupling. In order to ensure the passivity of the coupled reaction-diffusion neural networks, some adaptive strategies to tune the coupling strengths among network nodes are designed. By utilizing some inequality techniques and the designed adaptive laws, several sufficient conditions ensuring...
For the relative attitude control problem in phasing period of rendezvous and docking, attitude quaternion was adopted to describe the dynamic model and the kinematics equation of spacecraft. Then attitude quaternion PD feedback was designed to control the relative attitude successfully. On this basis, the sliding mode control was researched and used in relative attitude control to improve accuracy...
A new electro-hydraulic high-frequency flutter generator is designed and simulated. This paper introduced the structure and the working principle of the flutter generator firstly, then established the mathematical model of the generator. From the simulation waveform, the cutting force as the tool to withstand 8000N, the amplitude reaches 6μm, which is fully meet the requirements of VAM, and provide...
