Unformatted text preview: EE 141 Final 06/12/08 Duration: 3 hours The final is closed book and closed lecture notes. No calculators. You can use a single page of handwritten notes. Please carefully justify all your answers. Problem 1: The linearized equations describing the vertical of motion of a hot-air balloon are given by: 1 T =- T + u 2 z + z = aT + w were T represents the deviation of the hot-air temperature from the equilibrium temperature, z represents the altitude of the balloon, u represents the deviation of the burner heating rate from the equilibrium rate, and w is the wind speed. In what follows we will assume that w = 0 and to simplify the computations the parameters 1 , 2 , and a will assume the following unrealistic values: 1 = 0 . 1 2 = 0 . 2 a = 10 1. Compute the transfer function from the input u to the balloons altitude. 2. Design a compensator for a unity-feedback loop so that the steady-state error to a parabola is 0 . 2....
