Handling of tire pressure variation in autonomous vehicles: an integrated estimation and control design approach

Comparing to the traditional sequential design approach, the integrated structure and control design approach integrates the mechanical structure design and the control system design by formulating the design as an optimization problem. This paper investigates two important questions pertaining to the integrated structure and control design approach: Why and when should the integrated design approach be used rather than the traditional sequential design approach? In this paper, we have formulated both approaches as optimization problems. The benefit of the integrated design approach over the sequential design approach is proved in this paper. The conditions for when the integrated design approach will result in better closed-loop system performances are also given. A simple example is given to illustrate the theoretical results derived. The conclusion is given following this example and the simulation results are shown at the end of the paper.

This paper presents a novel modeling method for the control design of autonomous vehicle systems. The goal of the method is to provide a control-oriented model in a predefined Linear Parameter Varying (LPV) structure. The scheduling variables of the LPV model through machine-learning-based methods using a big dataset are selected. Moreover, the LPV model parameters through an optimization algorithm are computed, with which accurate fitting on the dataset is achieved. The proposed method is illustrated on the nonlinear modeling of the lateral vehicle dynamics. The resulting LPV-based vehicle model is used for the control design of path following functionality of autonomous vehicles. The effectiveness of the modeling and control design methods through comprehensive simulation examples based on a high-fidelity simulation software are illustrated.

After giving a short overview about the published instrumentation and control standards worldwide with regard to the separation measures, as released by the different safety authorities, this paper provides a first assessment of the different needs and requirements to be considered in the frame of separation measures which are to be implemented in the instrumentation and control design. According to this analysis the corresponding design aspects and features are derived and analyzed. The experience gained both in nuclear power plant modernization projects and new builds show that there are margins both for interpretation possibilities and for possible technical solutions, which can be proposed to the customer in order to fulfill the concerned standards. A conclusion about the design approach and solutions as well as possible future scenarios is given.
