The self-balancing robot and two geared, DC motor-driven wheels are the plant and actuators,respectively.The sensor suite includes a gyroscope that measures angular velocity and anaccelerometer that measures non-gravitational acceleration. Since the accelerometer and gyroare known to have systematic errors(bias, drifts, etc)and are noisy, the signals from the sensorsare combined to produce an accurate measurement of the orientation angle of the robotmore accurate than can be achieved with either sensor individually. The external referencecommands enter the control system via the host computer either through keyboard entry orfrontpanel commands sent over the network connection to the myRIO which hosts thePDcontroller code.The design goal is the balance the robot in an upright pose inthe presenceof external disturbances and to be robustly stable to plant variations(e.g,remain stable evenwhen a large mass is placed on the robot). The controller is a PD controller.Relative stab
