Constraint Based Planning with Composable Substate Graphs. [PDF]

, 2010
Constraint satisfaction techniques provide powerful inference algorithms that can prune choices during search. Constraint-based approaches provide a useful complement to heuristic search optimal planners.We develop a constraint-based model for cost ...

Tracking control of mechanical systems with a unilateral position constraint inducing dissipative impacts [PDF]

, 2012
In this paper, the tracking control problem is considered for mechanical systems with unilateral constraints with dissipative impacts. In these systems, impacts are triggered at the exact moment when the constraint becomes active.

A Viscoelastic Contact Problem with Adhesion and Surface Memory Effects

Mathematical Modelling and Analysis, 2014
We consider a mathematical model which describes the quasistatic contact between a viscoelastic body and an obstacle, the so-called foundation. The material's behavior is modelled with a constitutive law with long memory.

A quasistatic viscoplastic contact problem with normal compliance, unilateral constraint, memory term and friction ☆

, 2017
The goal of this paper is to deal with a mathematical model which describes the quasistatic frictional contact between a viscoplastic body and a foundation. The contact is modeled with normal compliance, unilateral constraint and memory term.

Analysis of a Unilateral Contact Problem with Normal Compliance

Annals of the West University of Timisoara: Mathematics and Computer Science, 2014
The paper deals with the study of a quasistatic unilateral contact problem between a nonlinear elastic body and a foundation. The contact is modelled with a normal compliance condition associated to unilateral constraint and the Coulomb's friction law ...

Prioritised fuzzy constraint satisfaction problems: axioms, instantiation and validation [PDF]

, 2003
This paper identifies a generic axiom framework for prioritised fuzzy constraint satisfaction problems (PFCSPs), and proposes methods to instantiate it (i.e., to construct specific schemes which obey the generic axiom framework).

Discrete Unilateral Constrained Extended Kalman Filter in an Embedded System

Sensors
Since its publication in the 1960s, the Kalman Filter (KF) has been a powerful tool in optimal state estimation. However, the KF and most of its variants have mainly focused on the state estimation of smooth systems.

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

Advanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...
