Full-order observer design for a class of port-Hamiltonian systems [PDF]

open access: yes, 2010
We consider a special class of port-Hamiltonian systems for which we propose a design methodology for constructing globally exponentially stable full-order observers using a passivity based approach.

Computer-based studies on bioprocess engineering : II - Tools for process operation [PDF]

open access: yes, 1996
In this paper we review recent advances on the practice and theory of process control with particular emphasis to the operation of bioreactors. We present in detail a case-study on the modelling, model-based identification and adaptive control of fed ...

Contact and channel modelling to support the early design of technical systems [PDF]

open access: yes, 2009
The early design of mechanical systems is critical because it constrains options later in the design process. In this early stage of the design process, designers must consider customer requirements, how they are related to system functionality and how ...

Interval Observer-based Fault Detection and Isolation for Quadrotor UAV with Cable-Suspended Load [PDF]

open access: yes
This paper proposes an actuator fault detection and isolation (FDI) scheme for quadrotor unmanned aerial vehicle (UAV) with cable-suspended load. First, a linear parametervarying (LPV) model of quadrotor UAV is established, in which the effects of cable-

Fault Separation Based on An Excitation Operator with Application to a Quadrotor UAV

open access: yes, 2023
This paper presents an excitation operator based fault separation architecture for a quadrotor unmanned aerial vehicle (UAV) subject to loss of effectiveness (LoE) faults, actuator aging, and load uncertainty.
