Adaptive landing deck control system and method for rotor-like aircraft

Abstract

The invention discloses a self-adaptive landing deck control system and method for a rotor-type aircraft. The system includes a base, a landing deck, a MEMS gyroscope, a Hook hinge, a hydraulic control valve, an ECU control center and a hydraulic controller. Three sets of Hooke hinges are evenly distributed along the circumference of the bottom surface of the landing deck. Three groups of Hooke hinges are evenly distributed along the circumference on the upper surface of the base. The base is mounted on the hull of the ship. Hook hinge groups on landing deck and base are staggered. The top end of the push rod of the hydraulic valve is connected to the landing deck through the Hook hinge, and the bottom end is connected to the base through the Hook hinge. Two MEMS gyroscopes are mounted on the landing deck and the base, respectively. When the aircraft lands, the signal of the MEMS gyroscope is transmitted to the ECU control center. After calculation, the control center transmits the instruction to the hydraulic controller. The hydraulic controller sends instructions to each hydraulic valve to adjust the length of the push rod of each hydraulic valve, so as to maintain the landing. The deck is always level and raised above the deck of the ship and maintains the same altitude. The system of the invention has stable performance and high control precision.

Description

Technical field [0001] The invention involves a rotor aircraft adapted to the falling deck control system and methods, which belongs to the horizontal stable technology field of rotor aircraft on the small and medium -sized carrier. Background technique [0002] With the development of the drone market in recent years, the rotor drone has quickly won the attention and love of consumer groups with the advantages of excellent control performance and the convenience of vertical take -off and landing. At present, the application of land -based rotor drones is very wide, but there are not many applications of carrier rotor drones. The main reason is that the rotor drone is very difficult to land on the shaking ship. Affected by the waves with the ship, it caused the posture to be unprecedented, and the unsuccessful incident of landing and slipping on the side caused major accidents such as the crash or the damage of the ship, and the casualties of the ship. Therefore, how to make the ...

[0004] This kind of stable platform with two-axis structure is driven by a servo motor. Since there is a single point of force between the support frame and the platform, once the load mass on the platform is large or the mass distribution is uneven, the entire mechanism will be affected by the frame mass. Factors such as unbalanced torque, frictional interference torque between shafts, and mechanical structure resonance are seriously affected, as well as random errors and noises of the gyroscope, which are important reasons that affect the inertial stability accuracy of the system. In addition to the difficulty in controlling the high precision of the mechanical structure and machining In addition to the high precision of the installation, it is also difficult to improve the dynamic and static stability performance indicators of the system through effective control strategies. The reason is that the dual-axis servo motor has a general effect on reducing the motion of the carrier (hull) itself, and the dynamic response speed of the system is up to It does not meet the requirements, and the actual application effect is mediocre. This structure is generally only used in scenes where the base is a fixed still life. It is difficult to use this structure on ships.
