Aerial Vehicle Return Control With In-Flight User Intervention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerial vehicles in auto return mode lack operational flexibility, as users cannot intervene or perform emergency actions during the return process, limiting their control and safety.
Innovation Solution
An aerial vehicle control method and system that adjusts power output based on both return point position information and flight control instructions received during the return process, allowing for flexible operation and user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the aerial vehicle operates in auto return mode, then the return process is automated and simple to operate, but the user cannot intervene or perform emergency actions during return
Solution Approach 1:
The system dynamically switches between two operational states: auto return mode for normal operation and manual control mode for intervention. The flight control system can transition from automated power output control based solely on return point position to manual control when flight control instructions are received, allowing the operational characteristics to be adaptive rather than fixed
Solution Approach 2:
The system implements feedback by continuously monitoring for flight control instructions during the return process. When instructions are detected, the system responds by adjusting power output according to these instructions, creating a closed-loop control mechanism that enables user intervention while maintaining the base auto return functionality
2Reliability
If the aerial vehicle follows a fixed return path to the return point, then the navigation is simple and reliable, but the vehicle cannot avoid obstacles or perform user-defined actions
Solution Approach 1:
The navigation system transitions from a static fixed-path approach to a dynamic path adjustment mechanism. The flight control system monitors for flight control instructions that may indicate obstacle detection or user-defined actions, and dynamically adjusts the return path accordingly, maintaining reliability through continuous monitoring while gaining adaptability through responsive path modification
3Device complexity
If the aerial vehicle uses automated power output control based on return point position, then the control system is simple, but the operational flexibility is limited
Solution Approach 1:
The flight control system is designed to perform multiple functions: it executes automated power output control based on return point position information, and simultaneously monitors for and processes flight control instructions. This multi-functionality allows a single control system to handle both simple automated returns and complex intervention scenarios without requiring separate dedicated systems
Solution Approach 2:
The control system incorporates feedback by continuously monitoring for flight control instructions during the return process. When instructions are detected, the system adjusts power output accordingly, creating a responsive control mechanism that maintains simplicity through a unified control architecture while achieving flexibility through feedback-driven adjustments

AI summary
An aerial vehicle control method includes detecting a flight control instruction during returning of an aerial vehicle to a return point along a return trajectory according to an auto return instruction. The flight control instruction determines a predetermined trajectory different from the return trajectory. The method further includes generating a superimposed instruction by superimposing return point position information indicating the return point and the flight control instruction. The superimposed instruction determines a flight trajectory that is an integration of the return trajectory and the predetermined trajectory and that is different from the return trajectory and the predetermined trajectory. The method also includes controlling the aerial vehicle to fly along the flight trajectory according to the superimposed instruction.
