Four-dimensional Gait Surfaces for A Tilt-rotor -- Two Color Map Theorem
Zhe Shen, Yudong Ma, Takeshi Tsuchiya
This article presents the four-dimensional surfaces which instruct the gait plan for a tilt-rotor. The previous gaits analyzed in the tilt-rotor research are inspired by animals; n…
Feedback Linearization Based Tracking Control of A Tilt-rotor with Cat-trot Gait Plan
Zhe Shen, Yudong Ma, Takeshi Tsuchiya
With the introduction of the laterally bounded forces, the tilt-rotor gains more flexibility in the controller design. Typical feedback linearization methods utilize all the inputs…
Cat-inspired Gaits for A Tilt-rotor -- from Symmetrical to Asymmetrical
Zhe Shen, Takeshi Tsuchiya
Among the tilt-rotors (quadrotors) developed in the last decades, Rylls model with eight inputs (four magnitudes of the thrusts and four tilting angles) attracted great attention.…
Gait Analysis for A Tilt-rotor: The Dynamic Invertible Gait
Zhe Shen, Takeshi Tsuchiya
Conventional Feedback-Linearization-based controller, applied to the tilt-rotor (eight inputs), results in the extensive changes in the tilting angles, which are not expected in pr…
Singular Zone in Quadrotor Yaw-Position Feedback Linearization
Zhe Shen, Takeshi Tsuchiya
It is well known that the conventional quadrotor is an under-actuated MIMO system. The number of the inputs is less than the degree of freedom. One approach in controlling this non…
The Pareto-frontier-based Stiffness of A Controller: Trade-off between Trajectory Plan and Controller Design
Zhe Shen, Takeshi Tsuchiya
Approaching a set goal for a UAV comprises a trajectory plan and a controller design (control after plan problems). The optimal trajectory (reference) is calculated before being tr…
