In complex naturalistic sensorimotor behaviour, uncertainty arises from ambiguities and
delays in sensory inputs as well as noise in sensory detection and motor execution. In …

Stick balancing on the fingertip is a complex voluntary motor task that requires the
stabilization of an unstable system. For seated expert stick balancers, the time delay is 0.23 …

The question of how the inverted position of a pendulum can be stabilized is of fundamental
importance for understanding human balancing tasks. Applications range from postural …

Background The ability to control lumbar extensor force output is necessary for daily
activities. However, it is unknown whether this ability is impaired in chronic low back pain …

The critical length that limits stabilizability for delayed proportional‐derivative‐acceleration
(PDA) feedback and for predictor feedback (PF) is analyzed for the inverted pendulum …

When balancing, instability can occur when the object being balanced moves at a rate that is
beyond the abilities of human motor control. This illustrates that responsiveness of motor …

In this work, we study the dynamic response of the most popular unstable control problem,
the inverted pendulum in terms of classical control theory. The theoretical and experimental …

A planar stick balancing task was investigated using stabilometry parameters (SP); a
concept initially developed to assess the stability of human postural sway. Two subject …

Patients with low back pain are suggested to follow a protective coping strategy. Therefore,
rehabilitation of these patients requires estimating their motor control strategies (the control …

Robust control theory studies the effect of noise, disturbances, and other uncertainty on
system performance. Despite growing recognition across science and engineering that …
