Work Vehicle Actuator Synchronization via Velocity Ratios
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work vehicle control systems often result in inefficient and inaccurate movement of implements due to sequential or step-wise actuation of actuators, leading to slow and inefficient operation.
Innovation Solution
A control system that synchronously operates multiple actuators by receiving operation selections with associated velocity ratios, determining a limiting actuator based on control effort proportions, and adjusting acceleration parameters to optimize actuator movement, allowing for simultaneous and efficient movement of implements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If sequential or step-wise actuation of actuators is used, then control simplicity is maintained, but operation speed and efficiency deteriorate
Solution Approach 1:
The control system dynamically adjusts velocity ratios and acceleration parameters for each actuator based on real-time control effort proportions, enabling adaptive coordinated control that optimizes operation speed while managing system complexity through algorithmic rather than hardware complexity
Solution Approach 2:
The system changes control parameters (velocity ratios, acceleration parameters) dynamically during operation based on the limiting actuator's control effort proportion, allowing the actuators to operate in a coordinated manner that improves speed without requiring complex hardware modifications
2Productivity
If sequential actuation of actuators is used, then system complexity is reduced, but productivity deteriorates
Solution Approach 1:
The control system dynamically adjusts velocity ratios and acceleration parameters based on control effort proportions, enabling all actuators to work simultaneously in a coordinated fashion, thereby improving productivity through optimized parameter management rather than hardware complexity
Solution Approach 2:
The system employs dynamic coordinated control where velocity ratios and acceleration parameters are continuously adjusted based on the limiting actuator's control effort, allowing multiple actuators to operate in parallel and improve overall productivity
3Manufacturing precision
If synchronous actuation of multiple actuators is implemented, then operation accuracy is improved, but control complexity increases
Solution Approach 1:
The system achieves precise coordinated control by dynamically adjusting velocity ratios and acceleration parameters based on control effort proportions, improving movement precision through algorithmic parameter optimization rather than complex hardware control mechanisms
