For the uncertain impact of ship air wake and deck motion to the landing process, the traditional automatic carrier landing system lacks flexibility and accuracy. This paper designs fuzzy controller for automatic carrier landing of aircraft. The application examined is a F/A-18 Fuzzy Logic Automatic Carrier Landing System (FACLS). The FACLS has seven inputs, two outputs, and several hundred fuzzy...
Voltage differential feedback control system based on repetitive control is proposed in this paper. The scheme, which can improve the dynamic characteristic and steady state performance by Capacitor voltage as outer loop while its differential as inner loop without current sensor, is achieved on a three-phase PV inverter with TMS320F2808. Two different control strategies, traditional and repetitive...
System identification combined with free-running model tests or full-scale trials is a kind of effective methods to determine the hydrodynamic derivatives in the mathematical models of ship manoeuvring motion. On-line support vector machines is proposed to identify ship manoeuvring motion model and ship motion first-order response model based on free-running model tests and full-scale trials, respectively...
For the needs of the rehabilitation training of lower limbs, a wire-driven aid-walking robot is proposed, and the kinematic research is done in this paper. This aid-walking robot is designed according to the skeletal structure of lower limbs of the normal person. After this, the kinematic model of this system is built based on D-H method. By this model, the relationship between the length of wires...
