1. 1. On Complexity Certification of Active-Set QP Methods with Applications to Linear MPC

   Författare :Daniel Arnström; Daniel Axehill; Anders Hansson; Mikael Johansson; Linköpings universitet; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In model predictive control (MPC) an optimization problem has to be solved at each time step, which in real-time applications makes it important to solve these efficiently and to have good upper bounds on worst-case solution time. Often for linear MPC problems, the optimization problem in question is a quadratic program (QP) that depends on parameters such as system states and reference signals. LÄS MER

3. 2. Real-Time Certified MPC : Reliable Active-Set QP Solvers

   Författare :Daniel Arnström; Daniel Axehill; Anders Hansson; Linköpings universitet; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In Model Predictive Control (MPC), optimization problems are solved recurrently to produce control actions. When MPC is used in real time to control safety-critical systems, it is important to solve these optimization problems with guarantees on the worst-case execution time. LÄS MER

4. 3. Applications of Integer Quadratic Programming in Control and Communication

   Författare :Daniel Axehill; Anders Hansson; Anders Rantzer; Linköpings universitet; []
