There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
The objective of the proposed research is developing a novel contention-resolving model predictive controller to co-design optimal priorities and control laws which minimize the overall performance degradation caused by contentions in coupled control systems with constrained resources. The co-design problem is formulated as a mixed integer optimization problem with a very large search space, rendering difficulty in computing the optimal solution. To solve the problem, the proposed contention-resolving model predictive control algorithm can dynamically assign priorities and compute an optimal control. The priority assignment can be determined using a sample-based approach without excessive demand on computing resources and optimal controls can be computed iteratively following the order of the assigned priorities. The proposed contention-resolving model predictive control can be proved to find the optimal solution. The effectiveness of the proposed method will be verified through both simulations and experiments considering multiple practical applications.
