Stabilization on Null Controllable Region

2019
A set of equilibrium points in a null controllable region is obtained based on an important assumption. A stable equilibrium line is given for DOSs subject to actuator saturation . A complex controller is constructed to achieve global stabilization of DOSs with actuator saturation .

Null-space impedance control with disturbance observer

2012 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2012
In this paper a new approach for the null-space impedance control of a kinematically redundant robot is proposed. The approach is useful for the case where the robot experience an external interaction on the body, especially in the presence of humans. The proposed algorithm guarantees safe and dependable physical interaction of the robot body with the ...

Null controllability of linear systems with control restraints

1971 IEEE Conference on Decision and Control, 1971
This paper provides some necessary conditions and some sufficient conditions for the null controllability of constant linear systems and a class of time-varying linear systems. The approach provides geometrical interpretations of the usual algebraic criteria and gives insight into the effects of restrained controls.

Null controllability and exact controllability for parabolic equations

2006
Which functions can be final states of a system described by a homogeneous parabolic differential equation? For inhomogeneous boundary conditions this is the problem of characterizing the set R of states reachable by boundary control. We construct more spaces of reachable states.
