Aircraft Flight Direction Control Using a Polar Coordinate Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft control systems face difficulties in accurately controlling unmanned aircraft, especially when the aircraft is far away or has a complex structure like a four-axis configuration, as users struggle to determine the real-time orientation and attitude of the aircraft, making it hard to interpret flight direction instructions effectively.
Innovation Solution
The method involves determining a relative position relationship between the aircraft and a control device, establishing a polar coordinate system with the control device as the origin, and receiving flight direction control instructions based on this system, allowing the aircraft to adjust its flight path without needing to consider its real-time attitude, by varying length or angle values accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional control system is used to control aircraft, then the control system can function, but the user cannot accurately determine the real-time orientation and attitude of the aircraft, making it hard to interpret flight direction instructions
Solution Approach 1:
The patent introduces a polar coordinate system as an intermediary between the user and the aircraft control system. This coordinate system, with the control device as origin, serves as a mediator that translates user instructions into aircraft movement commands, eliminating the need for users to directly interpret complex aircraft orientation and attitude data.
Solution Approach 2:
The patent transforms the traditional three-dimensional aircraft control problem into a two-dimensional polar coordinate system problem. By representing aircraft position and orientation in terms of radial distance and angular position relative to the control device, the system simplifies the control dimensionality and makes it easier for users to understand and manipulate.
2Adaptability or versatility
If the aircraft is far away or has a complex structure like four-axis configuration, then the aircraft can perform complex maneuvers, but the user struggles to determine real-time orientation and attitude
Solution Approach 1:
The polar coordinate system acts as an intermediary that simplifies the detection and measurement of aircraft orientation and attitude. Instead of directly measuring complex three-dimensional orientation data from the aircraft, the system measures the aircraft's position and angular orientation relative to the control device in the polar coordinate system, which is much easier to detect and interpret.
3Manufacturing precision
If the user must consider the aircraft's real-time attitude for control, then precise control can be achieved, but the control complexity increases significantly
Solution Approach 1:
The polar coordinate system serves as an intermediary that decouples control precision from control complexity. The system maintains precise control by accurately tracking the aircraft's position and angular orientation in the polar coordinate system, while the control interface remains simple because users only need to understand two-dimensional polar coordinates rather than complex three-dimensional aircraft attitude parameters.
