Disturbance/Uncertainty Estimator Based Robust Control of Nonminimum Phase Systems
(Institute of Electrical and Electronics Engineers Inc., 2018-08)
An open problem in disturbance/uncertainty estimator based control is to obtain explicit mathematical expressions for robust stability, performance, and bandwidth requirement. This paper offers a path based on H-infinity ...
A stability-guaranteed smooth-scheduled MIMO robust emergency autopilot for a lateral surface jammed UAV
(SAGE Publications Ltd, 2018-09-01)
This paper investigates a methodology for autopilot design for an unmanned air vehicle where one of the lateral control surfaces, i.e. the aileron or rudder, becomes jammed and unusable. The autopilot handles the automatic ...
Scheduled smooth MIMO robust control of aircraft verified through blade element SIL testing
(SAGE Publications Ltd, 2018-01-01)
This paper demonstrates a multi-input multi-output (MIMO) robust control approach where multiple scheduled designs are merged to produce a smooth control law. The design is verified using software-in-the-loop (SIL) testing ...
Robust Temperature Control of a Thermoelectric Cooler via -Synthesis
(Springer New York LLC, 2018)
In this work robust temperature control of a thermoelectric cooler (TEC) via -synthesis is studied. An uncertain dynamical model for the TEC that is suitable for robust control methods is derived. The model captures ...
Disturbance/Uncertainty Estimator Based Integral Sliding-Mode Control
(IEEE-Inst Electrical Electronics Engineers Inc, 2018-11)
A disturbance/uncertainty estimator based integral sliding-mode control approach is introduced. Explicit mathematical expressions for robust stability, performance, and bandwidth requirement are derived. The integral ...
Nonlinear modelling and control of the flow over aerofoils using CFD simulations
(Elsevier B.V., 2016-09)
A simulation based approach for nonlinear dynamical modelling and feedback control of the drag to lift ratio for aerofoils is investigated through case studies involving NACA 23012, ag13 and b737a aerofoils. The flow around ...
Performance improvement of a photovoltaic system using a controller redesign based on numerical modeling
(Pergamon-Elsevier Science Ltd, 2016-08-03)
This paper focuses on the utilization of numerical modeling and simulation to improve the performance of a theoretically designed stand-alone photovoltaic (PV) system with constant DC voltage. A theoretically designed ...
MIMO nonlinear modeling and robust control of standalone dc photovoltaic systems
(Pergamon-Elsevier Science Ltd, 2017-07-13)
Multiple-input multiple-output (MIMO) modeling and simulation techniques are utilized to boost the usefulness of a common DC-output photovoltaic (PV) system. Vast studies in the literature are mostly based on single-input ...
Design of a flight stabilizer system and automatic control using HIL test platform
(International Journal Of Mechanical Engineering And Robotics Research, 2016)
In this paper a Hardware-In-the-Loop (HIL) test platform is used to design a flight stabilization system for Unmanned Aerial Vehicles (UAV). Controllers are first designed and tested separately for lateral and longitudinal ...
Comparing and Developing PID and sliding mode Controllers for Quadrotor
