1. 1. Structure-Exploiting Numerical Algorithms for Optimal Control

   Författare :Isak Nielsen; Daniel Axehill; Anders Hansson; Eric Kerrigan; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical Optimal Control; Model Predictive Control; Riccati Recursion; Parallel Algorithms; Low-Rank Modifications; Parametric Programming; Optimization; Explicit MPC; Moving Horizon Estimation; Partial Condensing;

   Sammanfattning : Numerical algorithms for efficiently solving optimal control problems are important for commonly used advanced control strategies, such as model predictive control (MPC), but can also be useful for advanced estimation techniques, such as moving horizon estimation (MHE). In MPC, the control input is computed by solving a constrained finite-time optimal control (CFTOC) problem on-line, and in MHE the estimated states are obtained by solving an optimization problem that often can be formulated as a CFTOC problem.

4. 3. On Structure Exploiting Numerical Algorithms for Model Predictive Control

   Författare :Isak Nielsen; Daniel Axehill; Anders Hansson; Pontus Giselsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : One of the most common advanced control strategies used in industry today is Model Predictive Control (MPC), and some reasons for its success are that it can handle multivariable systems and constraints on states and control inputs in a structured way. At each time-step in the MPC control loop the control input is computed by solving a constrained finite-time optimal control (CFTOC) problem on-line. LÄS MER

5. 4. Distributed optimization for the optimal control of electric vehicle fleets

   Författare :Rémi Lacombe; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Platooning; Optimal control; Electric vehicles; Public transit; Distributed optimization;

   Sammanfattning : Owing to their absence of tailpipe emissions and their independence from fossil fuels, Electric Vehicles (EVs) are currently experiencing a rapid deployment in an attempt to curb global greenhouse gas emissions. EV operation represents a technical challenge, however, as new control algorithms need to be developed to address their limited driving range and their longer charging times. LÄS MER
