Observed practices of design engineers

International Journal of Mechanical Engineering Education, 2023
While there are numerous studies documenting the skills and abilities of experienced designers and engineers, research is needed to document the specific practices or behaviors of design engineers, a subset of creative engineers who solve complex problems.

Observer Backstepping Design for Flight Control

Engineering Proceedings, 2023
This paper presents observer backstepping as a new nonlinear flight control design framework. Flight control laws for general-purpose maneuvering in the presence of nonlinear lift and side forces are designed.

A New Observer Design for the Joint Estimation of States and Unknown Inputs for a Class of Nonlinear Fractional-Order Systems

Mathematics
This article designs an observer for the joint estimation of the state and the unknown input for a class of nonlinear fractional-order systems (FOSs) such that one portion satisfies the Lipschitz condition and the other does not necessarily satisfy such ...

Pole placement design for quantum systems via coherent observers

, 2015
We previously extended Luenberger's approach for observer design to the quantum case, and developed a class of coherent observers which tracks linear quantum stochastic systems in the sense of mean values.

Sampled-data sliding mode observer for robust fault reconstruction: A time-delay approach [PDF]

, 2014
A sliding mode observer in the presence of sampled output information and its application to robust fault reconstruction is studied. The observer is designed by using the delayed continuous-time representation of the sampled-data system, for which ...
