A self stabilizing platform

Abstract

There exist mechanical devices for which it is important to retain a constant position, or a constant direction regardless of their space fitting. Classic applications of such systems include a camera stabilization in moving systems, a platform stabilization for mobile guidance systems, or other special cases. For this and other cases, it is appropriate to use the now widespread and relatively accurate MEMS gyroscopes and accelerometers. Their consumption and size are negligible and can be used right from the smallest models or toys. This paper reports on a particular solution build on the sensor MPU6050 and its parameters that can scan 6DOF (3 × 3 accelerometer + gyroscope). In real conditions this task is not trivial, since the signals of these sensors are quite noisy and influenced by other variables such as reaction speed, inertia, and accuracy of data interpretation, sensor drift and others. Self-stabilizing platforms can be of great use especially in the automotive, aviation, marine, robotics, aerospace as well as in everyday life.
