Abstract
In this work, we propose a control system based on a Fuzzy Control in order to counter the chaotic Nano-satellite and position motion. The control is founded on the variation of angular acceleration from which the torque of an inertial system is modified. A disk and a DC motor compose the inertial system. We develop a fuzzy control algorithm for each axis, x, y. For each control algorithm, we include information in both directions x and y, and with their combination we get the control of the third axis. This control system can be adequate for using in low-orbit satellites. Through of an accelerometer we obtain the information of the axis x, y. To test the fuzzy control proposed, we built a scale model with the standard dimensions of a CubeSat. In this scale model was included the inertial system with the accelerometer and the tests of the fuzzy control conducted were under conditions of gravity on the Earth's surface. The control variables are specified by the value given by the accelerometer as input variable, and the pulse width of the DC current as output variable. The processed information by the fuzzy control is sent to the DC motors, which handle the disks, generating the torque required to steady the chaotic and position of Nano-satellite movement.
