Automated design synthesis of mechatronic vehicles with integrated control systems

本研究的目的是开发一种改进的方法，机电一体化车辆集成控制系统（ICS），包括差动制动控制，主动转向控制和主动侧倾力矩控制的自动化设计综合。该方法将用于自动化的车辆的设计综合，使机械和控制子系统将同时优化。这种提出的新方法将建立在申请人以前在机电一体化车辆设计方法学方面的研究基础上。在现有的方法中，一个原始的设计问题被分解成一个两级优化。然而，这种方法是不适合的设计综合的机电一体化车辆与ICS。其原因有二：一是系统级的优化算法难以协调大量的设计准则和约束条件，这是由于原始系统设计在唯一的子系统级上被分解为许多子系统设计;二是从功能设计的角度来看，集成控制系统经常被分解为多层次的体系结构。

This research aims at developing an improved method for the automated design synthesis of mechatronic vehicles with integrated control systems (ICSs), involving differential braking control, active steering control and active roll moment control. The method will be used for automating the design synthesis of vehicles so that the mechanical and control subsystems will be simultaneously optimized. This proposed new approach will build upon the applicant's previous research in design methodologies of mechatronic vehicles. In the existing methodology, an original design problem is decomposed into a two-level optimization. However, this methodology is not suitable for the design synthesis of mechatronic vehicles with ICSs. The reasons for this are twofold: firstly, the optimization algorithm at the system level has difficulties coordinating a large number of design criteria and constraints, resulting from the decomposition of the original system design into the many subsystem designs at the only subsystem level; secondly, from the perspective of functional design, the integrated control systems are frequently decomposed into multi-level architectures.
