Design method of electronic stabilization system based on six-degree-of-freedom motion platform

Abstract

The invention discloses a design method of an electronic stabilization system based on a six-degree-of-freedom motion platform, and belongs to the technical field of mechanical design, automation and the like. The method comprises the following steps: 1) obtaining attitude information of a carrier (aircraft) through a gyroscope and an acceleration sensor; 2) converting the attitude information into an electric signal and transmitting the electric signal through an integrated circuit; 3) establishing a six-degree-of-freedom motion control system based on a computer PCI bus by a DSP + FPGA architecture; 4) establishing a linear error model, and performing error correction; and (5) designing a core mechanical structure of the six-degree-of-freedom seat. In the flight process of the aircraft, the damping seat automatically adjusts the state of the seat in a three-dimensional space according to the swinging, pitching and rotating states of the aircraft, so that the relative posture of the seat and the ground surface is kept unchanged, and the damping effect is achieved. The passenger using the aircraft damping seat does not feel uncomfortable due to speed change, turning and take-off and landing acceleration of the aircraft, and really feels smooth flight.

Description

Technical field [0001] The present invention belongs to the mechanical design, the field of automation technology, and particularly relates to integrated circuits and sensor applications motion control system design method of an attitude control system, electronic stability based on the six degrees of freedom for movement of the platform. Background technique [0002] Most conventional aircraft passenger seat does not have the damper function, a shift in the carrier aircraft, swings, the front and rear tilt, and rotation acceleration generated on a certain direction, when the angular acceleration, the passenger seat on the body will follow side to side, front and rear pitch, causing discomfort, experience a sense of decline. [0003] How posture information obtained by the sensor; how the orientation information to the processor in a form of electrical signals transmitted by the integrated circuit; how to establish six degrees of freedom motion control system; how the correction ...

AI Technical Summary

Problems solved by technology

[0002] Most of the existing manned aircraft seats do not have the shock absorption function. When the aircraft carrier changes speed, swings from side to side, pitches back and forth, and rotates to generate acceleration and angular acceleration in a certain direction, the passengers on the seat will also follow the body. Shaking left and right, pitching back and forth, causing discomfort and reducing the user experience
