Consistent Initial Conditions for Unstructured Higher Index DAEs: A Computational Study
نویسندگان
چکیده
Differential algebraic equations (DAEs) are implicit systems of ordinary differential equations, F (x′, x, t) = 0, for which the Jacobian Fx′ is always singular. DAEs arise in many applications. Significant progress has been made in developing numerical methods for solving DAEs. Determination of consistent initial conditions remains a difficult problem especially for large higher index DAEs. This paper looks at one approach for computing consistent initial conditions for these systems. The focus is on initializing higher index DAE integrators but the observations are relevant to the general problem of initialization of DAE integrators.

Constraint Preserving Integrators for General Nonlinear Higher Index Daes
In the last few years there has been considerable research on numerical methods for diierential algebraic equations (DAEs) f(x 0 ; x; t) = 0 where f x 0 is identically singular. The index provides one measure of the singularity of a DAE. Most of the numerical analysis literature on DAEs to date has dealt with DAEs with indices no larger than three. Even in this case, the systems were often assu...
متن کاملIllustrative Study on Linear Differential Equations and Matrix Polynomials
The objective of this paper is to study the theoretical analysis of linear differential-algebraic equations (DAEs) of higher order as well as the regularity and singularity of matrix polynomials. Some invariants and condensed forms under appropriate equivalent transformations are established for systems of linear higher-order DAEs with constant and variable coefficients. Inductively, based on c...
متن کاملExtending explicit and linearly implicit ODE solvers for index-1 DAEs
Nonlinear differential-algebraic equations (DAE) are typically solved using implicit stiff solvers based on backward difference formula or RADAU formula, requiring a Newton-Raphson approach for the nonlinear equations or using Rosenbrock methods specifically designed for DAEs. Consistent initial conditions are essential for determining numeric solutions for systems of DAEs. Very few systems of ...
متن کاملNumerical solution of higher index DAEs using their IAE's structure: Trajectory-prescribed path control problem and simple pendulum
In this paper, we solve higher index differential algebraic equations (DAEs) by transforming them into integral algebraic equations (IAEs). We apply collocation methods on continuous piece-wise polynomials space to solve the obtained higher index IAEs. The efficiency of the given method is improved by using a recursive formula for computing the integral part. Finally, we apply the obtained algo...
متن کاملOptimal control for unstructured nonlinear differential-algebraic equations of arbitrary index
We study optimal control problems for general unstructured nonlinear differential-algebraic equations of arbitrary index. In particular, we derive necessary conditions in the case of linear-quadratic control problems and extend them to the general nonlinear case. We also present a Pontryagin maximum principle for general unstructured nonlinear DAEs in the case of restricted controls. Moreover, ...
