Unformatted text preview: ME 260 Homework #3 MEASUREMENT TECHNIQUES March 1, 2007 Dr. B. Zhang (Instructor) Office Hours 8:00-10:00 (Mon &Wed) UTE Building, Room 384 and by appointment Phone: 486-2072 zhang@engr.uconn.edu 1. A system is modeled by the equation ( 29 t F y y = + . Initially, the output signal is steady at 100 V. The input signal is suddenly increased to 150 V. a. Determine the response equation. b. On the same graph, plot both the input signal and the system time response until a steady response is reached. FIND : y ( t ) SOLUTION : The solution to the system model was given by the general form, ( 29 ( 29 [ ] t e y y y t y- - + = where here, y (0)=100 units, y =150 units, and =1 s. then, units 50 150 t t e y-- = Alternatively, by direct solution ) ( 150 t U y y = + for t + , ( 29 B Ce y y t y t p h + = + =- By substitution, B =150. Then, if y (0)=100, C =-50. ( 29 t e t y-- = 50 150 2. Suppose a thermometer is known to have a time constant of 50 s in a particular application.
