A bi-population immune algorithm for weapon transportation support scheduling problem with pickup and delivery on aircraft carrier deck

The ability of ensuring the safety and reliability of combat aircraft in noncombat processes is a must for aircraft sortie generation. How to guarantee the operation safety and reliability of combat aircraft while ensuring operation efficiency in the air is a matter requiring further exploration and research. For this reason, this paper carries out dynamic planning of aircraft sortie generation based on multiobjective optimization. First, this paper selected a few indicators for measuring the congestion of air field and constructed a state demarcation model; then, it constructed an operating state identification model for the sortie generation and established objective functions for the aircraft runway sequencing model based on the scheduling time span and takeoff and landing delay time loss of the aircraft. At last, this paper elaborated on the methods of landing aircraft parking space scheduling and runway optimization, and the effectiveness of the general model was verified by experimental results, which can be applied to both field-based and cargo-based aircraft sortie generation problems.

Dynamic Planning of Aircraft Sortie Generation Based on Multiobjective Optimization

Optimization, of fixed aviation support resource station configuration for aircraft carrier based on aircraft dispatch mission scheduling

In this work, a switching linear quadratic integral (LQI) controller based on fuzzy logic is designed for the load-factor tracking problem of high-performance aircraft referred to as the Aero-Data Model in Research Environment (ADMIRE). ADMIRE is a new generation aircraft and has a wide flight operation envelope in terms of altitude and speed. Hence, it is difficult to design a flight controller to achieve a high tracking performance. First, the LQI controller is selected due to good tracking performance and robustness in the model dynamics. Combining switching LQI controller and fuzzy logic improves the transient performance of the closed-loop switched system. The results obtained with the fuzzy switching controller have been compared with the conventional LQI and the switching LQI in terms of robust demand tracking. The simulation results have demonstrated that the fuzzy switching controller is superior to the conventional LQI and switching LQI controllers due to better transient performance and robust stability.

The invention designs a three-connecting-rod type marine self-grabbing and releasing mechanical arm device capable of actively controlling constant tension. The device mainly comprises a base, a balance platform, a left balance arm, a right balance arm, a tension sensor, a first connecting rod, a second connecting rod, a third connecting rod, a left auxiliary balance arm, a right auxiliary balancearm, a main sling, a left balance cable, a right balance cable, a left auxiliary balance cable, a right auxiliary balance cable, a visual sensor, a lifting ring, a grab hook and a PLC control box. Four balance cables are adopted, active constant tension control is achieved through a PLC, and automatic grabbing, collecting and releasing functions are achieved through the grab hook of the visual sensor. The device has the advantages that a multi-degree-of-freedom three-connecting-rod type mechanical arm is used, and the grabbing range is enlarged. Meanwhile, the influence of marine environmental factor interference force on the main sling, the grab hook and the hoisted object is considered. The four balance cables are adopted, so that the stabilization effect is improved. The visual sensoris applied, the marine mechanical arm can automatically grab, collect and release the hoisted object, and compared with a manually-operated marine crane, the device is more intelligent and suitable for various carriers.
