1. Introduction

- Final objective of the course

Reduce pendulum vibration and stabilize faster.

- Motivation

By reducing vibration, reduce load on structure. We can adapt this to airplane wing or drones.

2. Theory

- Compound pendulum equation of motion

- Pole locations

If point is left side of Imaginary axis, convergence

If point is right side of Imaginary axis, divergence

Distance between point to center means speed to convergence or divergence.

If point is far from the center, faster to convergence or divergence.

In boundary [-pi,+pi] angle that made between x axis and the line connected to point

called Arg z

This angle is for make only one Polar Coordinate system.

3. Experimental setup

L=0.215m

d=0.1m

m=0.017kg

4. Experimental results
