Real Time PID Control Of Wireless Two-Wheeled Balancing Lego EV3 Robot
Keywords:Real-time PID controller, Two-wheeled Lego EV3 Robot, Upright Stability,
AbstractResearch on balancing two-wheeled robot has gained interest among researchers due to its highly nonlinear characteristic. The objective of this project is to control the stability of a two-wheeled EV3 Lego robot and maintain in the upright position while performing linear motion as well steering right/left and moving up/down a ramp. In this project, a twowheeled balancing Lego EV3 robot is modelled in a state space and controlled by a PID controller. The robot is controlled in real time via Matlab/Simulink interface using Graphical User Interface (GUI) and the robot performance can be observed wirelessly at the same time using Wi-Fi connection between the robot and MATLAB. The two-wheeled EV3 Lego robot is able to stay in the upright position while performing steering and going up/down the ramp. The analysis of the system plant has been made in terms of overshoot, settling time of tilt angle stabilization using simulation approach and successfully controlled using real two-wheeled EV3 hardware.
