Question: AP10.1 A three-axis pick-and-place application re quires the precise movement of a robotic arm in three-dimensional space, as shown in Figure AP10.1 for joint 2.
AP10.1 A three-axis pick-and-place application re
quires the precise movement of a robotic arm in three-dimensional space, as shown in Figure AP10.1 for joint 2. The arm has specific linear paths it must follow to avoid other pieces of machinery. The over
shoot for a step input should be less than 13%.
(a) Let G s c( ) = K, and determine the gain K
that satisfies the requirement. Determine the re
sulting settling time (with a 2% criterion).
(b) Use pole-zero cancellation to reduce the settling time to
Ts ≤ 5 s.
