Unformatted text preview: University of Maryland at College Park Dept. of Aerospace Engineering ENAE 432: Aerospace Control Systems Problem Set #3 Issued: 11 Feb. 2011 Due By: 18 Feb. 2010 You should be able to solve all problems on this homework using only your calculator, pen, and paper. Matlab may be used instead, but only to perform complex number calcu- lations or to find polynomial roots. Any Matlab work must be documented by including a printed diary of the calculations. Any Matlab solution that uses laplace , ilaplace , dsolve , or any other Matlab functionality save for complex number arithmetic and the roots command will be marked incorrect. Any solution in which all calculations are not explicitly documented will be marked incorrect (i.e. you must show all your work). Question 1: A linear system has dynamics governed by the transfer function G ( s ) = s 2 + 5 s + 4 ( s + 2)( s + 3)( s 2 + 2 s + 5) The system has initial conditions y (0) = y (3) (0) = 0, ˙ y (0) = 1, ¨ y (0) =- 1, and is subjected to the input...
