ECE 382 Homework 3 Due: Thursday, January 21, 2010 1) Find the control ratios C 1 ( s ) R 1 ( s ) , C 1 ( s ) R 2 ( s ) , C 2 ( s ) R 1 ( s ) , and C 2 ( s ) R 2 ( s ) for the block diagram shown below. Use Mason’s gain formula. R 1 1 – H 1 1 – H 2 1 C 1 G 2 G 1 G 3 R 2 1 G 4 1 C 2 – H 4 – H 3 1 2) Find the transfer function C ( s ) R ( s ) for the block diagram shown below. Use Mason’s gain for- mula. G 1 G 2 G 3 H 2 H 1 H 3 R(s) + _ + _ + _ C(s) G 4 H 4 _ _ G 5 + 3) A gear-train system is shown below. The moments of inertia of gears are lumped as J 1 , J 2 , and J 3 , and they are assumed to be negligible.
