Structure Preserving Reduced Attitude Control of Gyroscopes
Nidhish Raj, Leonardo J. Colombo, Ashutosh Simha
We design a reduced attitude controller for reorienting the spin axis of a gyroscope in a geometric control framework. The proposed controller preserves the inherent gyroscopic sta…
Attitude Control of a Novel Tailsitter: Swiveling Biplane-Quadrotor
Nidhish Raj, Ravi Banavar, Abhishek +1
This paper proposes a solution to the attitude tracking problem for a novel quadrotor tailsitter unmanned aerial vehicle called swiveling biplane quadrotor. The proposed vehicle de…
Robust Attitude Tracking for Aerobatic Helicopters: A Geometric Approach
Nidhish Raj, Ravi N Banavar, Abhishek +1
This paper highlights the significance of the rotor dynamics in control design for small-scale aerobatic helicopters, and proposes two singularity free robust attitude tracking con…
Attitude Tracking Control for Aerobatic Helicopters: A Geometric Approach
Nidhish Raj, Ravi N. Banavar, Abhishek +1
We consider the problem of attitude tracking for small-scale aerobatic helicopters. A small scale helicopter has two subsystems: the fuselage, modeled as a rigid body; and the roto…
