Controllability and Observability Conditions for Impulsive DAEs on Time Scales
Asian Journal of Control, EarlyView.ABSTRACT This paper establishes criteria for controllability and observability in a class of linear time‐invariant impulsive differential‐algebraic equations (DAEs) defined on a time scale. Controllability is defined as the ability to transfer the system state from any initial condition to any desired state within a finite time interval using an ...

Symbolic Computations in Multibody Systems [PDF]
, 1994 Symbolic formula manipulation has proven to be an efficient tool in the dynamical analysis of multibody systems. A multibody system data base is introduced and its implementation using a CAD-3D-software is shown. Starting from the data base the equations of motion are generated by a coordinate partitioning approach combined with the projection ...

Symbolic Computation of the Inverse Dynamics of Elastic Joint Robots [PDF]
, 2004 Efficient calculation of the inverse dynamics of robotic mechanisms serves as a basis for a variety of control schemes. Classical algorithms for rigid multibody systems do not apply when more realistic modeling is required. The computational treatment of

Vibration Attenuation of Cantilever Beam Using Electromagnetic Delayed Feedback
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This study presents a combined analytical and numerical investigation of a single‐input single‐output delayed feedback controller designed to suppress vibrations in a cantilever beam actuated by an electromagnet positioned beneath its free end. An analytical model was developed using the linearized equation of motion for a transversely excited

A Direct Eigenanalysis of Multibody System in Equilibrium [PDF]
Journal of Applied Mathematics, 2012 This paper presents a direct eigenanalysis procedure for multibody system in equilibrium. The first kind Lagrange’s equation of the dynamics of multibody system is a set of differential algebraic equations, and the equations can be used to solve the equilibrium of the system.
