Stochastic Nonlinear Model Predictive Control with Probabilistic Constraints Ali Mesbah 1, Stefan Streif; 2, Rolf Findeisen, and Richard D. Braatz Abstract Stochastic uncertainties are ubiquitous in complex dynamical systems and can lead to undesired variability of system outputs and, therefore, a notable degradation of closed-loop performance.

    We develop appropriate notions of invariance and stability for such systems and provide terminal conditions for stochastic model predictive control (SMPC) that guarantee mean-square stability and robust constraint fulfillment of the Markovian switching system in closed-loop with the SMPC law under very weak assumptions. The main idea of Model Predictive Control (MPC) is to use a model of the plant to predict the future evolution of the system [15]. At each sampling time, an optimal control problem is solved over a finite horizon. The optimal command signal is applied to the process only during the following sampling interval. At the next time step a new.

Introduction. Model Predictive Control (MPC) is nowadays a standard in many industrial contexts, see e.g., due to its ability to cope with complex control problems and to the availability of theoretical results guaranteeing feasibility and stability properties, reasons have motivated the many efforts devoted to develop MPC algorithms robust with respect to unknown, but.

Model Predictive Control describes the development of tractable algorithms for uncertain, stochastic, constrained systems. The starting point is classical predictive control and the appropriate formulation of performance objectives and constraints to provide guarantees of closed-loop.

An MPC model generates control commands by solving an open-loop finite-horizon constrained optimal control within a prediction horizon, implementing the first time step only in an iterative way (Bertsekas, ; Rawlings and Mayne, ).

Most existing MPC-based CACC models focus on free-flow or light traffic conditions in a deterministic system. states.

A stochastic model predictive control (SMPC) design approach is proposed to optimize closed-loop performance while enforcing constraints. Conditions for stochastic convergence and robust constraints fulfillment of the closed-loop system are enforced by solving linear matrix inequality problems off line.

Abstract: The topic of this paper is model predictive control (MPC) for max-plus linear systems with stochastic uncertainties the distribution of which is supposed to be known. We consider linear constraints on the inputs and the outputs. Due to the uncertainties, these linear constraints are formulated as probabilistic or chance constraints, i.e., the constraints are required to be satisfied.

Abstract: In this paper we propose a stochastic model predictive control (MPC) formulation based on scenario generation for linear systems affected by discrete multiplicative disturbances. By separating the problems of (1) stochastic performance, and (2) stochastic stabilization and robust constraints fulfillment of the closed-loop system, we aim at obtaining a less conservative control.

Recent developments in stochastic MPC provided guarantees of closed loop stability and satisfaction of probabilistic and hard constraints. However the required computation can be formidable for anything other than short prediction horizons. This difficulty is removed in the current paper through the use of tubes of fixed cross-section and variable scaling.

Abstract—In this paper we evaluate closed-loop stochastic model predictive control techniques on a nonlinear high density polyethylene fluidized bed example. Closed-loop MPC is a control strategy in which one optimizes feedforward signals while maintaining back-off to inequality constraints on the process variables.

This back-off is kept. However, as explained above, there are many more properties that capture closed-loop performance. One such property, particularly important for constrained model predictive control (MPC) systems, is the satisfaction of various inequality constraints.
