Motion control and vibration suppression of flexible lumped systems via sensorless LQR control [PDF]

open access: yes, 2011
This work attempts to achieve motion control along with vibration suppression of flexible systems by developing a sensorless closed loop LQR controller. Vibration suppression is used as a performance index that has to be minimized so that motion control ...

Modeling the Interaction Between two-Wheeled Self-Balancing Vehicle and its Rider

open access: yesInternational Journal of Applied Mechanics and Engineering, 2013
The paper presents a modeling method and mathematical description of a two-wheeled self-balancing vehicle and its rider. A model of the rider that was used contains a model of the ankle joint, so we could determine the interaction between the rider and ...

“Lives and times”: The case for qualitative longitudinal research in anatomical sciences education

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Qualitative longitudinal research (QLR) focuses on changes in perceptions, interpretations, or practices through time. Despite longstanding traditions in social science, QLR has only recently appeared in anatomical sciences education (ASE).

Adaptive mixing formation control of multiquadrotor unmanned aerial vehicle systems

open access: yesAsian Journal of Control, EarlyView.
Abstract This paper presents a distributed adaptive mixing control (AMC) design for formation maintenance of systems of multiquadrotor UAVs (q‐UAVs) during commanded path‐tracking maneuvers. The proposed formation control scheme has a two‐level structure. The high level defines the desired trajectories for rigid and persistent formation acquisition and

A Model Reference Adaptive Control Approach to Terrain Following Flight Control System

open access: yesDüzce Üniversitesi Bilim ve Teknoloji Dergisi
Automatic Flight Control System (AFCS) Terrain Following (TF) mode allows military aircraft to fly at a certain altitude above ground level at a low altitude. TF mode reduces the probability of aircraft detection by enemy airborne radars.

Optimum Weight Selection Based LQR Formulation for the Design of Fractional Order PI{\lambda}D{\mu} Controllers to Handle a Class of Fractional Order Systems

open access: yes, 2013
A weighted summation of Integral of Time Multiplied Absolute Error (ITAE) and Integral of Squared Controller Output (ISCO) minimization based time domain optimal tuning of fractional-order (FO) PID or PI{\lambda}D{\mu} controller is proposed in this ...
