This problem assumes our standard unity (H(s) = 1) negative feedback closed-loop control system. The given open-loop transfer function is 2 ( ) ( 2) G s s s . Using denominator parameter matching, design a PD (proportional-derivative) controller ( ) G s K Ks C PD to achieve a closed-loop overdamped second-order response with 1s 2 and 2 s 4 . What is the resulting numerical closed-loop transfer function T(s)? For a unit step input R(s) and assuming 1.0 is the desired steady-state output value, determine the closed-loop correction factor, if one is required. Determine the pre-filter transfer function ( ) G s P , if one is required. Given a unit step input R(s), sketch the open-loop and input-corrected, pre-filtered closed-loop output responses, assuming zero initial conditions for both cases.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
