In this project you will design a controller for a quad-rotor with the objective of regulating its altitude. we will assume that a controller is already in place to ensure the quad-rotor can only move up and down. 1. write the equations of motion for the quad-rotor assumed to be a point mass that can only move along a vertical line and is subjected to the action of two forces: gravity and thrust. 2. knowing that there are 4 propellers, and that each propeller produces a trust force given by: tw 1.536x 10-7ns2 and w is the propeller's t cr is given by cr where the thrust coeffhicien rotational speed, compute the value of w required to make the quad-rotor hoover when its total mass is 0.027 kg Physics, 22.06.2019 13:50, eminh5145
Two boxes, with mass m1 and m2, are connected by a very light string over a frictionless pulley. let the mass on the track be m1 (in the experiment that will be the dynamic cart plus force sensor) and the hanging mass be m2 (that is mass hanger and mass added). using newton’s laws, find the tension in the string in terms of the masses (m1 and m2) and other known constants. find also the acceleration.
