چکیده

This work presents an explicit–implicit procedure to compute a model predictive control (MPC) law with guarantees on recursive feasibility and asymptotic stability. The approach combines offline-trained fully-connected neural network online primal active set solver. provides input initialization while the method ensures is trained primal–dual loss function, aiming generate sequences that are feasible meet desired level of suboptimality. Since alone does not guarantee constraint satisfaction, its output used warm start online. We demonstrate this scales large problems thousands optimization variables, which challenging for current approaches. Our achieves 2 × reduction in inference time compared best benchmark suite different solver strategies.

Decentralized Adaptive Control of Large-Scale Non-affine Nonlinear Time-Delay Systems Using Neural Networks

In this paper, a decentralized adaptive neural controller is proposed for a class of large-scale nonlinear systems with unknown nonlinear, non-affine subsystems and unknown nonlinear time-delay interconnections. The stability of the closed loop system is guaranteed through Lyapunov-Krasovskii stability analysis. Simulation results are provided to show the effectiveness of the proposed approache...

Model predictive control of large scale processes

Model predictive control is a receding horizon control policy in which a linear or quadratic program with linear constraints is solved on-line at each sampling instance. An algorithm is developed that allows quick computation of suboptimal control moves. The linear constraint set is approximated by an ellipsoid and a change of variables is performed so that a solution may be computed eciently ...

Neural Networks in Model Predictive Control

ABSTRACT The contribution is aimed at predictive control of nonlinear processes with the help of artificial neural networks as the predictor. Since this methodology is relatively wide, paper only concentrates on the prediction via artificial neural networks. Special attention is paid to the usage of offline-learnt predictor based on multilayer feed forward neural network. The proposed method is...
