Unformatted text preview: MAE 171a Homework Problem Set 2 - Revised July 1st, 2:30PM Prof. Schwartz Due: Wednesday, July 7th 1. Sketch the output time response of a step input to the following transfer functions. Use partial fractions to decompose the response. (a) G ( s ) = 20 ( s +5)( s +10) (b) G ( s ) = 20( s +4 . 5) ( s +5)( s +10) (c) G ( s ) =- s +1 s 2 +4 s +1 2. The response of a system, y ( t ) to an input, u ( t ) , is given by ¨ y ( t ) + 5 ˙ y + 6 y ( t ) = u ( t ) . (a) Convert the system into a state space equivalent Define the state vector x = bracketleftbigg y ˙ y bracketrightbigg .
