This MPC (Model Predictive Controller) project, was the last in term 2 of the Udacity Self Driving Car Engineer Nanodegree. To demonstrate the potential of the TS-MPC we propose a comparison between three methods of solving the kinematic control problem: using the non-linear MPC formulation (NL-MPC), using TS-MPC without updating the prediction model and using updated TS-MPC with the references of the planner. An MPC (multi point constraint) is more like an SPC (single point constraint), in that it modifies instead of adds to the matrices that describe the model in order to describe the special behavior of these MPCs. 带model predictive control (MPC)的constrained optimization。 基于NN的感知方法对不确定性缺乏反馈信息,所以深度学习和贝叶斯理论结合可以给出不确定性的估计。 将感知和规划集成,构成了end-to-end planning。不过,对自动驾驶而言,这种方案风险比较高。. to multi-variable systems, MPC can handle underacuated problem gracefully by combining all the objectives into a single objective function. In this paper, we present a general scheme, based on the well-known model predictive control paradigm, for implementing the tile motion planner for complex vehicle dynamical models. In addition, the results of the biofidelity rating obtained by applying the rating system also supported good agreement of most of the kinematic parameters. Optimization of the NN is performed within a receding horizon model predictive control (MPC) framework, subject to dynamic and kinematic constraints. The new driver model is based on the well-known two-point visual driver model, and it uses a model predictive control (MPC) module in the anticipatory. We implemented this kinematic model in Simulink, using it as a foundation for the controller design.
