Abstract: Distributed Model Predictive Control (MPC) aims to transfer the success of centralized MPC to cyber-physical systems. Cooperative approaches with multiple communication rounds between coupled subsystems promise high performance by solving a centralized optimal control problem online. However, real-time requirements only allow for few optimizer iterations and the resulting suboptimal control inputs reduce performance and complicate the stability analysis. Similar challenges have been successfully addressed in centralized Nonlinear MPC (NMPC) by Real-Time Iteration (RTI) schemes. We present an RTI approach for distributed NMPC via tailored decentralized optimization algorithms and obtain novel stability guarantees for coupled nonlinear systems. Experimental results with robot formations demonstrate the efficacy and real-time feasibility of the proposed approach.
