Seesaw Dynamics and Control- Experimental Study

Abstract

Dynamics and attitude control of a seesaw is described in this study. At first, mechanical design of the system is completed in Solid Works. Then the system is made. To control the system dynamic is studied. Furthermore, a number of electric components such as motor, electronic speed controller, micro controller board are also studied and selected for the experimental setup. Finally, proportional integral derivative controller (PID) algorithm is used to control the seesaw. Gain values of the PID controller are estimated on the basis of trial and error method. Ultimate values of the proportional, integral and derivative gains are 3.05, 0.005 and 0.75 respectively. During experiment, it is found that, system takes only five seconds to reach the same position as the input command. Therefore, this technique can be used to control the roll and pitch attitude of different unmanned aerial vehicles.
