A rest solution, p, of a control system is said to possess controlled stability if for each t1>0 a full nbd. of points of p can be steered to p in time t1 by solutions of the system. Equivalently, if the system acts in a linear space and p is the origin, this states the domain of « null controllability » is open. We consider systems of the form\(X\left(

Control of locomotor stability in stabilizing and destabilizing environments
Gait & Posture, 2017To develop effective interventions targeting locomotor stability, it is crucial to understand how people control and modify gait in response to changes in stabilization requirements. Our purpose was to examine how individuals with and without incomplete spinal cord injury (iSCI) control lateral stability in haptic walking environments that increase or ...

Geometric stability in force control
Proceedings. 1991 IEEE International Conference on Robotics and Automation, 2002Previous implementations of robot force control seldom produced satisfactory results, and researchers in the past have experienced significant instability problems associated with their force controllers. When a manipulator is constrained to an environment (force-controlled), geometric stability due to the manipulator configuration and the force ...

Stabilizing controller for an hydraulic servomechanism
2007 European Control Conference (ECC), 2007This paper deals with the problem of the control of an hydraulic servomecanism process. More precisely, a result on feedback stabilization of an hydraulic cylinder driven by a servovalve is given. It concerns the case when in the considered model the behavior of the servovalve is taken into account.

In this chapter we shall present the theoretical foundations of control synthesis for two-leg locomotion systems. Because of the presence of unpowered degrees of freedom (d.o.f.), the most serious problem which has to be solved is the overall system stability. This is the reason why the control synthesis at two stages has been adopted.

Stability and controllability are the basic properties of a dynamical system. Since a multicopter without control feedback is unstable, an autopilot is required to guarantee its stability and further make the multicopter hover automatically without any need for an external intervention.

In 2004, Hirschi redefined self-control by using the framework of his social control theory while retaining assumptions of his original self-control theory. A few studies have provided supportive evidence for the relationship between the newly defined self-control and deviant behavior, whereas no study has tested stability hypothesis by using this new ...
