可控约束Hamilton系统的Lie对称性与守恒量研究
Lie symmetries and conserved quantities of controllable constrained Hamilton system
摘要
Abstract
This paper investigated the Lie symmetries and conserved quantities of singular systems with control-lable constrained parameters in phase space, which can lay the foundation for the design of advanced control strategies for singular systems. The controllable constraints were treated as external and usually nonholonomic constraints. Considering the consistency between the constraint and the inherent constraints of the system, the author presented the canonical equations of the controllable constrained Hamilton system. Based on the total derivative calculation of arbitrary mechanical quantities along the trajectory system, the author provided the de-termination equations,the limiting equations and the additional limiting equations for the determination of the Lie symmetry of the Hamilton system with controllable constraints by using the invariance of differential equations and algebraic equations under infinitesimal transformations. By constructing the conditional structure equation satisfied by norm functions, the author obtained the form of conserved quantities by Lie symmetry of controllable singular systems in phase space.Finally,an example for the application was given.关键词
