Abstract
In this paper, the performance of inverted pendulum have been Investigated
using robust control theory. The
robust controllers used in this paper are H∞ Loop Shaping Design Using
Glover McFarlane Method and mixed
H∞ Loop Shaping Controllers. The mathematical model of Inverted Pendulum,
a DC motor, Cart and Cart
driving mechanism have been done successfully. Comparison of an inverted
pendulum with H∞ Loop Shaping
Design Using Glover McFarlane Method and H∞ Loop Shaping Controllers
for a control target deviation of an
angle from vertical of the inverted pendulum using two input signals
(step and impulse). The simulation result
shows that the inverted pendulum with mixed H∞ Loop Shaping Controller
to have a small rise time, settling
time and percentage overshoot in the step response and having a good
response in the impulse response too.
Finally the inverted pendulum with mixed H∞ Loop Shaping Controller
shows the best performance in the
overall simulation result.
