A Simplified Vehicle Dynamics Model for Motion Planner Designed by Nonlinear Model Predictive Control

چکیده
Motion planning by considering it as an optimal problem is effective and widely applicable method. Its comprehensive performance greatly depends on the vehicle dynamics model, which highly coupled nonlinear, especially under dynamical scenarios causes much more consumption of computation resources for numerical optimization. To increase real time motion planner designed nonlinear model predictive control (NMPC), a unified simplified (SDM) presented to make balance between accuracy complexity driving scenarios. Based statistical analysis results naturalistic conditions, set up, considers tyre cornering characteristic also conditions with large turning angle. After validation this (CDM) comparisons other used models variety coupling effect analyzed according transfer functions, are obtained linearizing CDM at equilibrium points. Furthermore, SDM derived ignoring weak part effect. The validated several comparative studies further applied design NMPC validate its contribution improvement conditions.

Improved Optimization Process for Nonlinear Model Predictive Control of PMSM
Model-based predictive control (MPC) is one of the most efficient techniques that is widely used in industrial applications. In such controllers, increasing the prediction horizon results in better selection of the optimal control signal sequence. On the other hand, increasing the prediction horizon increase the computational time of the optimization process which make it impossible to be imple...

متن کاملRobust Model Predictive Control for a Class of Discrete Nonlinear systems
This paper presents a robust model predictive control scheme for a class of discrete-time nonlinear systems subject to state and input constraints. Each subsystem is composed of a nominal LTI part and an additive uncertain non-linear time-varying function which satisfies a quadratic constraint. Using the dual-mode MPC stability theory, a sufficient condition is constructed for synthesizing the ...
