Chapter 3, Problem 25

(choose chapter or problem)

Experiments to identify precision grip dynamics between the index finger and thumb have been performed using a ball-drop experiment. A subject holds a device with a small receptacle into which an object is dropped, and the response is measured (Fagergren, 2000). Assuming a step input, it has been found that the response of the motor subsystem together with the sensory system is of the form

\(G(s)=\frac{Y(s)}{R(s)}=\frac{s+c}{\left(s^2+a s+b\right)(s+d)}\)

Convert this transfer function to a state-space representation.
