Owing to the competitive advantages of fast response speed, large pushing force, high reliability, and precision, permanent magnet linear synchronous motor (PMLSM) has played an increasingly vital role in various high-speed high-precision control systems. However, PMLSM exhibits nonlinear behavior actual operation, position tracking precision is negatively affected by friction, load changes, ot...

In this paper control of a flexible joint manipulator is designed using an adaptive output-feedback controller based on a backstepping design. The parameters of system are assumed to be unknown and only motor position and link position measurements are used for the synthesis of the controller. A canonical state representation of the system is derived and filters are designed to obtain the estim...

Provenance, the metadata that pertains to the derivation history of a data product starting from its original sources, has become increasingly important in scientific workflow environments. In many cases, both data products and their provenance can be sensitive and effective access control mechanisms are essential to protect their confidentiality. In this paper, we propose i) a formalization of...
