Generic Synchronized Motion Control of Multiple Flying Vehicles

Motion synchronization addresses the cooperative or coordinated schemes of multi-composed systems when they work in an integrated fashion and are required to show the same kind of dynamic behaviour. It requires high accuracy regulation of motion states such as the position, velocity and orientation. Therefore, the challenge lies in its synchronized control strategy and real-time communications among the multi-composed systems.

The Opportunity

With the ever-increasing demand of efficiency and flexibility, many engineering intensive applications opt for using multi-composed systems to conduct cooperative tasks. Such applications are widely spread across industry sectors, e.g., the multi-robot systems in automotive industry, the multi-actuated platforms in manufacturing, and formation flying of multiple flight vehicle or spacecraft (satellites) in aerospace.

The Solution

A synchronized control using the cross-coupling strategy takes tracking actions by feeding back coupling errors. It creates interconnections that render mutual synchronization of involved multi-system motions. The strategy ensures stability and simultaneous convergence. However, there are still limitations in its implementation and operations.

The Technology

It consists of a parameter matrix that includes choices of synchronization and their quantitative values. It allows for control strategy modifications without changing the overall architecture. The numerically searchable parameter matrix also allows for performance improvement, optimization, or constraint when necessary. The strategy is demonstrated in motion synchronization among multiple flying vehicles, but is generic enough for other coordinated systems applications.
