Coordinated Industrial Drives With Dynamic Leader-Follower Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial drive systems for motorized equipment, such as pumps, struggle with coordinating multiple drives to maximize efficiency and extend the useful life of the equipment, as existing systems lack dynamic leadership and follower configurations to optimize task distribution and resource allocation.
Innovation Solution
A coordinated drive system with a leader-follower structure, where a processor dynamically selects a leader drive based on priority lists, configures follower drives, and reallocates tasks to ensure efficient operation and even wear among drives, using communication channels like Ethernet for real-time updates and task distribution.

Engineering Contradiction Analysis
1Productivity
If multiple drives operate independently without coordination, then each drive can operate at full capacity, but the overall system efficiency decreases and equipment life is reduced due to uneven wear
Solution Approach 1:
The system implements dynamic leader-follower configuration where drives can switch roles based on operational conditions. The leader drive dynamically adjusts follower drive configurations and task distribution in real-time, allowing the system to adapt to changing conditions while maintaining optimal efficiency and even wear distribution across all drives.
Solution Approach 2:
A centralized controller acts as an intermediary between multiple drives, coordinating their operations. The controller receives task requests, determines optimal leader-follower configurations, and distributes tasks appropriately, enabling efficient coordinated operation without requiring direct communication between all drive pairs.
2Ease of operation
If a fixed leader drive is assigned, then task distribution is simplified, but system adaptability decreases when drive conditions change
Solution Approach 1:
The leader-follower configuration is dynamically determined rather than fixed. The controller evaluates drive conditions, capabilities, and operational status in real-time to assign leadership roles, ensuring the system adapts to changing conditions while maintaining simple task distribution through the current leader.
Solution Approach 2:
The system continuously monitors drive status and performance, using this feedback to dynamically adjust leader-follower assignments. When drive conditions change, the controller receives feedback and reconfigures the leadership structure accordingly, maintaining both operational simplicity and system adaptability.
3Power
If drives operate without coordinated task distribution, then individual drive capacity is maximized, but overall resource allocation efficiency decreases
Solution Approach 1:
The centralized controller serves as an intermediary that optimizes resource allocation across all drives. It receives task requests, evaluates the capabilities and current status of each drive, and distributes tasks to achieve optimal overall resource utilization while maintaining individual drive capacity utilization.
Solution Approach 2:
The system dynamically changes operational parameters such as task distribution ratios, speed settings, and power allocation based on real-time drive conditions. This allows the system to maximize resource allocation efficiency while ensuring each drive operates within its optimal capacity range.

AI summary
An industrial device includes an input/output module and a processor. The input/output module is configured to communicate with one or more other devices via an industrial network. The processor is configured to configure the industrial device as a leader device or a follower device. The processor includes a leader module, upon being activated, configured to detect and configured one or more follower devices connected to the industrial network; and a follower module, upon being activated, configured to broadcast identity and receive configuration command from a leader device.
