On Prediction Model Fidelity in Explicit Nonlinear Model Predictive Vehicle Stability Control

نویسندگان

چکیده

This study discusses vehicle stability control based on explicit nonlinear model predictive (NMPC) and investigates the influence of prediction fidelity controller performance. The solutions are generated through an algorithm using multiparametric quadratic programming (mp-QP) approximations (mp-NLP) problems. Controllers with different models assessed objective indicators in sine-with-dwell tests. analysis considers following features: 1) lateral tire forces as functions slip angles, which essential for operation at limit handling. Moreover, a simple force saturation is shown to be effective alternative more complex simplified version Magic Formula; 2) longitudinal load transfers, playing crucial role accurate their yaw moment contributions; 3) coupling between forces, has significant front-to-rear distribution braking by controller; 4) peak stiffness factors model, visible yet negligible effects results.

Computational Aspects of Approximate Explicit Nonlinear Model Predictive Control

It has recently been shown that the feedback solution to linear and quadratic constrained Model Predictive Control (MPC) problems has an explicit representation as a piecewise linear (PWL) state feedback. For nonlinear MPC the prospects of explicit solutions are even higher than for linear MPC, since the bene…ts of computational e¢ ciency and veri…ability are even more important. Preliminary st...

Explicit robust model predictive control using recursive closed-loop prediction

In this paper, we develop an algorithm to compute robust MPC explicit solutions for constrained MIMO systems with internal uncertainties and external disturbances. Our approach is based on a recursive closedloop prediction strategy to realize a finite horizon robust MPC regulator, which has the feature that only one-step state prediction is sufficient to realize robust MPC with an arbitrary pre...

Symmetric Explicit Model Predictive Control ?

We exploit symmetry to reduce the memory storage requirements of linear explicit model predictive controllers. In the first part of the paper we define controller symmetry. We describe how symmetry can be used to compress the explicit controller and discuss the implementation of the resulting compressed controller. In the second part we develop a method for computing the reduced-memory controll...
