The оbjective оf Questiоns 10-12 is to formulаte а visuаl servo controller for a single degree of freedom positioning device. The positioning device may be modeled as a double integrator (1/s2) system with acceleration u as control input. The vision system is capable of updating the position information at a rate of 100 Hz with a latency of 10 milliseconds, which can be taken as a pure time delay (see the figure below). Show that the input-output transfer function (Y(z)/U(z)) is of the form
