Nonlinear PDE control of two-link flexible arm with nonuniform cross section
(IEEE, 2006-06)A two-link flexible arm with nonuniform or variable cross-section by design will be considered based on an exact PDE model with boundary conditions. In this research, the nonlinear controller is used to achieve set-point ... -
Observer based control of chaos
(IEEE, 1997-08)In this work we consider the control of forced chaotic oscillators. To obtain any desirable behavior, the system parameters are effectively modified using state feedback. The system states used in the feedback are estimated ... -
Observer based friction cancellation in mechanical systems
(IEEE, 2014-10)An adaptive nonlinear observer based friction compensation for a special time delayed system is presented in this paper. Considering existing delay, an available Coulomb observer is modified and closed loop system is formed ... -
On the boundary control of a flexible robot arm
(IEEE, 2001)We consider a flexible robot arm modeled as a single flexible link clamped to a rigid body. We assume that the system performs only planar motion. For this system, we pose two control problems; namely, the orientation and ... -
On the boundary control of beam equation
(IFAC, 2002)A flexible system described by Euler-Bernoulli beam equation is considered. The beam is clamped at one end, and is free at the other end. Boundary control force and torque inputs are applied at the free end of the beam. ... -
On the boundary control of Kirchhoff's nonlinear string
(IFAC, 2007)In this paper we propose two new classes of controllers which stabilize Kirchhoff's nonlinear string by using boundary control techniques. We assume that the boundary displacement is the only available measurement. The ... -

On the strain feedback control of a flexible robot arm
(IEEE, 2011)We consider a flexible robot arm modeled as a rigid hub which rotates in an inertial space; a light flexible link is clamped to the rigid body at one end and is free at the other. We assume that the flexible link performs ... -
Orientation and control of a flexible spacecraft: planar motion
(IEEE, 1990)We consider a flexible spacecraft modeled as a rigid body which rotates in an inertial frame; a light flexible beam is clamped to the rigid body at one end and free at the other end. We assume that the flexible spacecraft ... -
PDE control of a rotating shear beam with boundary feedback
(IEEE, 2009-08)We consider a flexible structure modeled as a shear beam which is clamped to a rigid body at one end and is free at the other end. The whole structure is free to rotate on the horizontal plane. We first model the system ... -
Reactive footstep planning for a planar spring mass hopper
(IEEE, 2009-10)The main driving force behind research on legged robots has always been their potential for high performance locomotion on rough terrain and the outdoors. Nevertheless, most existing control algorithms for such robots ... -
Robust LQ control for harmonic reference/disturbance signals
(IEEE, 2000)Linear Quadratic (LQ) controller design is considered for continuous-time systems with harmonic signals of known frequencies and it is shown that the design is reducible to an interpolation problem. All LQ optimal loops ... -
Robust stabilization of the wave equation against small delays
(IEEE, 1994)In this paper we consider a system which can be modeled by (undamped) wave equation in a bounded domain. We assume that the system is fixed at one end and is controlled by a boundary controller at the other end. We also ... -
Stability of delayed feedback controllers for discrete time systems
(IEEE, 2003)We consider the delayed feedback control (DFC) scheme for one dimensional discrete time systems. To analyze the stability, we construct a map whose fixed points correspond to the periodic orbits of the system to be controlled. ... -
