Abstract
Fast as possible (time optimal) single joint movements throughout the body
are characterized by the triphasic (3 pulse) pattern of activation in the
agonist and antagonist muscles. Simulation studies using a sixth order,
non-linear model were undertaken to determine the relationship between time
optimal movement and three pulse control. Exhaustive exploration of the
multidimensional space formed by descriptive parameters of the control
signal yielded control signals which drove the model to produce optimal
movements. The result of these one to two week computer simulation runs was
that if the limb is required to stay close to the target immediately after
the end of the control signal, the fastest movements are produced by a three
pulse control signal.
