Human Control in Rotated Frames: Anisotropies in the Misalignment Disturbance Function of Pitch, Roll, and Yaw
نویسندگان
چکیده
Comparative misalignment disturbance functions (MDF) have been measured for rotations between display and control axes for pure pitch, roll, and yaw misalignments in a high fidelity virtual environment. Twenty participants manually moved a virtual cursor using position control to touch 3-dimensionally, randomly presented nearby targets having a constant Fitts Index of Difficulty. Results show a peak disturbance near 120° of rotation for all axes with Roll being distinguishably more disturbed. Some reasons for observed anisotropies, nonlinearities and an equiaxial spiral feature are briefly discussed and modeled

OPTIMIZED FUZZY CONTROL DESIGN OF AN AUTONOMOUS UNDERWATER VEHICLE
In this study, the roll, yaw and depth fuzzy control of an Au- tonomous Underwater Vehicle (AUV) are addressed. Yaw and roll angles are regulated only using their errors and rates, but due to the complexity of depth dynamic channel, additional pitch rate quantity is used to improve the depth loop performance. The discussed AUV has four aps at the rear of the vehicle as actuators. Two rule bases...
متن کاملAngular sensitivities of volume gratings for substrate-mode optical interconnects.
The angular sensitivities of slanted volume gratings (VGs) illuminated by three-dimensional (3-D) converging-diverging spherical Gaussian beams for substrate-mode optical interconnects in microelectronics are analyzed by application of 3-D finite-beam rigorous coupled-wave analysis. Angular misalignments about the z, y, and x axes that correspond to yaw, pitch, and roll misalignments resulting ...

متن کاملRoll-Pitch-Yaw Integrated Robust Autopilot Design for a High Angle-of-Attack Missile
This paper explores the feasibility of roll–pitch–yaw integrated autopilots for a high angle-of-attack missile. Investigation of the aerodynamic characteristics indicates strong cross-coupling effects between the motions in longitudinal and lateral directions. Robust control techniques based on H1 synthesis are employed to design roll– pitch–yaw integrated autopilots. The performance of the pro...
متن کاملEnhancement of Articulated Heavy Vehicle Stability by Optimal Linear Quadratic Regulator (LQR) Controller of Roll-yaw Dynamics
Non-linear characteristic of tire forces is the main cause of vehicle lateral dynamics instability, while direct yaw moment control is an effective method to recover the vehicle stability. In this paper, an optimal linear quadratic regulator (LQR) controller for roll-yaw dynamics to articulated heavy vehicles is developed. For this purpose, the equations of motion obtained by the MATLAB sof...
