Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual control of UAVs during plant protection operations often results in flight deviations, making it difficult to accurately cover target areas, which affects the efficiency and accuracy of the operations.
Innovation Solution
A flight control method and device that determines a flight track, receives remote control signals, converts them into flight controlled quantities, and generates adjustment quantities to ensure the UAV stays on the track, using a PID controller for real-time corrections to maintain accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual remote control is used to operate the UAV, then the operator can control the flight direction, but the flight deviation accumulates over time and the UAV cannot accurately cover the target area
Solution Approach 1:
The system implements feedback control by continuously monitoring the UAV's actual flight position through positioning modules, comparing it with the predetermined flight track, and generating real-time correction signals. The correction amount is calculated based on the deviation between actual position and track position, which is then sent back to the flight control module to adjust the UAV's flight direction and maintain accurate track following.
Solution Approach 2:
The system introduces an intermediary correction mechanism between the manual control input and the UAV's actual flight. The correction calculation module acts as a mediator that processes both the operator's control commands and the position deviation data, generating adjusted control signals that combine manual intent with automated track correction, thereby reducing accumulated deviation while preserving operational control.
2Manufacturing precision
If autonomous flight mode is used, then the UAV can maintain accurate flight track, but the operator cannot make real-time adjustments to flight direction
Solution Approach 1:
The system merges autonomous track following capability with manual control authority by integrating the correction module into the flight control architecture. The correction amount calculated from position deviation is combined with the operator's remote control signals, creating a hybrid control mode that simultaneously maintains flight track accuracy and preserves real-time operational adjustment capability.
Solution Approach 2:
The system implements dynamic control by allowing the degree of automated correction to be adjusted during operation. The correction module can be dynamically tuned to provide different levels of intervention based on operational conditions, enabling the system to adapt between more autonomous behavior for track accuracy and more manual control for operational flexibility.
3Manufacturing precision
If continuous correction signals are sent to maintain flight track, then the UAV stays on the designated path, but the control system complexity increases
Solution Approach 1:
The control system is segmented into distinct functional modules: positioning module for acquiring UAV position, correction calculation module for computing deviation and correction amounts, and flight control module for executing corrections. This modular segmentation allows each component to perform its specific function independently, simplifying the overall system design and maintenance while maintaining precise flight path control through coordinated module operation.

AI summary
A flight control method and device of an Unmanned Aerial Vehicle (UAV), and a UAV. The method includes that: a flight track of the UAV is determined (101); a remote control signal sent by a remote control apparatus is received (102); the remote control signal is converted into a flight controlled quantity of the UAV (103); a flight adjustment controlled quantity of the UAV is generated according to the current location, the flight track and the flight controlled quantity, of the UAV (104); and a flight mission is executed according to an action indicated by the flight adjustment controlled quantity, as to enable the UAV to run on the flight track (105). When the flight of the UAV is manually controlled by using the remote control apparatus, according to a transverse adjustment controlled quantity, that the UAV does not yaw but flies on the correct track all the time in the case of a long flight can be ensured, thereby improving the flight accuracy.
