摘要: 针对智能车这类复杂的非完整约束机电系统的建模与控制,提出一种基于Udwadia-Kalaba理论和Udwadia控制框架的分类建模与控制方法。该方法包含被动约束和伺服约束两个部分,前者解决了基于Udwadia-Kalaba理论系统模型中的非完整约束问题,后者解决了基于Udwadia控制的系统近似轨迹跟踪控制问题。本文中将该方法应用于家用智能车系统,建立了较为精确的动力学模型和控制系统,并通过对电机的试验与仿真分析,验证了此种分类建模与控制方法的有效性。

Abstract: For the modeling and control of complex electromechanical system with nonholonomic constraints such as intelligent vehicles, a classification modeling and control method based on the Udwadia-Kalaba theory and the Udwadia control framework is proposed. The method consists of two parts, i.e. passive constraint and servo constraint. The former solves the problem of nonholonomic constraints in the system model based on Udwadia-Kalaba theory. The latter solves the problem of approximate trajectory tracking control based on Udwadia control. The method is applied to the home intelligent vehicle system, and an accurate dynamic model and control system is established. The effectiveness of the classification modeling and control method is verified by the test and simulation analysis of the motor
