Problem 1: The linearized equations describing the vertical motion of a hot-air balloon are given by:
\tau _(1)T^(?)=-T+u
\tau _(2)z^(¨)+z^(?)=aT+wwhere
Trepresents the hot-air temperature,
zrepresents the altitude of the balloon,
urepre- sents the burner heating rate, and
wis the wind speed. In what follows we will assume that
w=0and to simplify the computations the parameters
\tau _(1),\tau _(2), and
awill assume the following unrealistic values:
\tau _(1)=0.02,\tau _(2)=0.5,a=10Compute the transfer function from the input
uto the balloon's altitude. Design a controller for a unity-feedback loop so that the step response has no overshoot and the rise time is no greater than 0.9 seconds. solve for me
