WebTo overcome the bottleneck of traditional quadratic programming (QP) solvers, this paper proposes a robust penalty method (RPM) to solve an optimization problem in a linear MPC. The main idea of RPM is to solve an unconstrained QP problem using Broyden–Fletcher–Goldfarb–Shannon (BFGS) algorithm. shop with gwen https://chrisandroy.com
