Extension to the generalized lagrange formulation for nonlinear control

2021
Derived separately, the classical generalized Lagrange equations, demonstrates a variant of the Poincare's equations. With the use of generalized Lagrange equations, circuit modeling is extended to incorporate memristor elements and magnetically coupled circuits.

The Classical Formulations of Dynamics of Hamilton and Lagrange

2014
The present chapter is perhaps the place where our discourse meets more neatly the classic textbooks on the subject. Most classical books concentrate on the description of the formalisms developed by Lagrange and Euler on one side, and Hamilton and Jacobi on the other and commonly called today the Lagrangian and the Hamiltonian formalism respectively ...

The generalized Lagrange formulation for nonlinear RLC networks

IEEE Transactions on Circuits and Systems, 1982
Based on the concept of generalized Euler-Lagrange equations, this paper develops a Lagrange formulation of RLC networks of considerably broad scope. It is shown that the generalized Lagrange equations along with a set of compatibility constraint equations represents a set of governing differential equations of order equal to the order of complexity of

A contact formulation based on localized Lagrange multipliers: formulation and application to two‐dimensional problems

International Journal for Numerical Methods in Engineering, 2002
AbstractThe non‐penetration condition in contact problems is traditionally based on the classical Lagrange multiplier method. This method makes extensive use of modelling details of the contacting bodies for contact enforcement as the contact surface meshes are in general non‐matching.

Investigation of a New Formulation of the Lagrange Method for Constrained Dynamic Systems

Journal of Applied Mechanics, 1997
Lagrange multipliers are often used in order to model constrained dynamic systems. This method results in problems of constraints violations and therefore various methods of constraints stabilization have been presented in the past. The purpose of the present paper is to present a new formulation of the method that stabilizes the constraints, but ...
