A new suspended, mobile, remote-controlled video camera system to bring three-dimensional mobility to professional football is shown in Figure DP4.8(a) [29]. The camera can be moved over the field, as well as up and down. The motor control on each pulley is represented by the system in Figure DP4.8(b), where the nominal values are Ñ‚1 = 20 ms and Ñ‚2 = 2 ms.
(a) Compute the sensitivity STÑ‚1 and the sensitivity STÑ‚2.
(b) Design the controller gain K such that the steady-state tracking error to a unit step disturbance is less than 0.05.
