The objective of this lab is to develop a PID controller for pose and altitude stabilizer for a quadcopter, and investigate the stability of the controller using a statistical analysis. POSITION CONTROL OF AN UNMANNED AERIAL VEHICLE FROM A MOBILE GROUND VEHICLE By Astha Tiwari A THESIS Submitted in partial ful llment of the requirements for the degree of. Yes, that sounds like a good approach. MATLAB and Simulink are now being used extensively in not only academia as a teaching aid, a learning aid and a research tool but also industry for modeling, analysis, design and rapid prototyping. For stabilization of quadcopter, PID logic controller was chosen. Good day, I am currently creating an autonomous quadcopter using a cascading PID controller specifically a P-PID controller using angle as setpoints for the outer loop and angular velocities for the. The dynamics of a quadcopter were then modeled, analyzed, and linearized. Results show that active suspension system has better ability to reduce the pick overshoot of sprung mass and also provides better damping quality than passive suspension system.
