Method for creating digital circuits of a feedback control system that implements an approximation technique for model predictive control (MPC)

摘要

Method for creating digital circuits of an MPC controller (2), which implements an approximation technique for Model Predictive Control (MPC), in which a quadratic programming (QP) or linear programming (LP) optimization problem is formulated by starting from a model defined over a set of states of a state (x), wherein the said set of states is partitioned into simplices identified by vertices (v), and wherein said method comprises the steps of a) compute a solution (w*) of the optimization problem and define a control law (u(x)); b) check the stability under the control law (u(x)); c) synthesize a digital circuit by starting from the control law (u(x)) and the vertices (vi).

1. Method for creating digital circuits comprised in an MPC controller, which implements an approximation technique for Model Predictive Control (MPC), in which a quadratic programming or linear programming optimization problem is formulated based on a linear state-space dynamical model of a physical process having a state x, and provides a control law (u(x)) defined over a partition that contains simplices having vertices (vi,), where i ranges from 1 to Nv, and wherein the vertices (vi) are comprised in a given set of states of the physical process, wherein said method comprises the following steps:
a. compute a solution (w*) of the optimization problem and define the control law (u(x)); b. check the stability of a closed-loop system under the control law u(x), wherein the closed-loop system comprises the MPC controller and the physical process; and c. synthesize a digital circuit by starting from the control law (u(x)) and the vertices (vi).
