Adaptive control allocation for over-actuated systems with actuator saturation
(Elsevier B.V., 2017)This paper proposes an adaptive control allocation approach for over-actuated systems with actuator saturation. The methodology can tolerate actuator loss of effectiveness without utilizing the control input matrix estimation, ... -
Adaptive decentralized control of interconnected systems
(Watam Press, 2004)This paper presents a decentralized adaptive stabilization scheme for a class of interconnected systems using high-gain adaptive controllers. The nominal subsystems are assumed to satisfy some mild conditions required by ... -
Air fuel ratio control using delay resistant closed loop reference model adaptive control
(Hezarfen Havacılık ve Uzay Teknolojileri Enstitüsü, 2018)The focus of this paper is the air fuel ratio control of spark ignited engines. It is known that for an efficient removal of the pollutants from the exhaust gases, air fuel ratio has to be kept within a narrow band around ... -
Computable delay margins for adaptive systems with state variables accessible
(Institute of Electrical and Electronics Engineers Inc., 2017)Robust adaptive control of plants whose state variables are accessible in the presence of an input time delay is established in this paper. It is shown that a standard model reference adaptive controller modified with ... -
Control of uncertain sampled-data systems: An Adaptive posicast control approach
(Institute of Electrical and Electronics Engineers Inc., 2017)This technical note proposes a discrete-time adaptive controller for the control of sampled-data systems. The design is inspired from the Adaptive Posicast Controller (APC) which was designed for time-delay systems in ... -
Explicit adaptive time-delay compensation for bilateral teleoperation
(IEEE, 2015)This paper proposes a control framework that addresses the destabilizing effect of communication time-delays and system uncertainties in telerobotics, in the presence of force-feedback. Force feedback is necessary to obtain ... -
Fault tolerant control for over-actuated systems: an adaptive correction approach
(IEEE, 2016)This paper proposes an adaptive fault tolerant control allocation approach for over-actuated systems. The methodology does not utilize the control input matrix estimation to tolerate actuator faults and, therefore, the ... -
A fault tolerant vehicle stability control using adaptive control allocation
(ASME, 2018)This paper presents an integrated fault-tolerant adaptive control allocation strategy for four wheel frive - four wheel steering ground vehicles to increase yaw stability. Conventionally, control of brakes, motors and ... -
Gas generator pressure control in throttleable ducted rockets: a classical and adaptive control approach
(American Institute of Aeronautics and Astronautics (AIAA), 2015)This paper describes the control of gas generator pressure in throttleable ducted rockets using nonlinear adaptive control as well as classical control approaches. Simulation results using the full nonlinear and time-varying ... -
Nonlinear hierarchical control of a quad tilt-wing UAV: An adaptive control approach
(John Wiley and Sons Ltd, 2017)In this paper, a nonlinear hierarchical adaptive control framework is proposed for the control of a quad tilt-wing unmanned aerial vehicle (UAV). An outer loop model reference adaptive controller with robustifying terms ... -
On stability of interval matrices
(Institute of Electrical and Electronics Engineers, 1994-02)New sufficient, and sometimes necessary and sufficient conditions, are obtained for Schur- and Hurwitz-stability of interval matrices by relying on the concept of connective stability and M-matrices. The necessity part is ... -
On the discrete adaptive posicast controller
(IFAC, 2015)In this paper, we present the discrete version of the Adaptive Posicast Controller (APC) that deals with parametric uncertainties in systems with input time-delays. The continuous-time APC is based on the Smith Predictor ... -
Pressure control of gas generator in throttleable ducted rockets: a time delay resistant adaptive control approach
(Bilkent University, 2017-06)Having variable thrust during the operation of a rocket provides tremendous advantages while chasing down a target. For ducted rockets, the key factor to obtain variable thrust is the precise pressure control inside the ... -
Real time selection of scheduling rules and knowledge extraction via dynamically controlled data mining
(Taylor & Francis, 2010)A new scheduling system for selecting dispatching rules in real time is developed by combining the techniques of simulation, data mining, and statistical process control charts. The proposed scheduling system extracts ... -
Robust adaptive sampled-data control of a class of systems under structured nonlinear perturbations
(Institute of Electrical and Electronics Engineers, 1997-04)A robust adaptive sampled-data feedback stabilization scheme is presented for a class of systems with nonlinear additive perturbations. The proposed controller generates a control input by using high-gain static or dynamic ...
