Modelling an angular accelerometer using frequency-response measurements

A characterization of an angular accelerometer sensor is performed with a frequency- response experiment. To assess angular accelerometer dynamic properties, a position-based calibration table is utilized to provide the excitation input. The angular accelerometer specifications and calibration table limitations dfine a constrained test envelope...

Motion Simulator 2-Axis Input Design for Angular Accelerometer Calibration

The calibration of Angular Accelerometers requires a controlled test with a known acceleration profile. However, current turn-tables have been designed primarily for generating a constant rotational velocity. To generate a profile with varying angular acceleration we propose using constant rotational velocity on the two axes of a 2-axes motion...

Fundamental issues in manual control cybernetics

Manual control cybernetics aims to understand and describe how humans control vehicles and devices, such that more effective human-machine interfaces can be designed. Current cybernetics theory is primarily based on technology and analysis methods developed in the 1960s and has shown to be limited in its capability to capture the full breadth of...

Design of test signals for identification of neuromuscular admittance

The human neuromuscular system can be seen as a versatile and extremely adaptive actuator. Through co-contraction and reex modulation, the properties of the neuromuscular system can be modified, leading to a change in movement response to externally applied forces. These properties are normally expressed in the form of the neuromuscular...

Objective ARX Model Order Selection for Multi-Channel Human Operator Identification

In manual control, the human operator primarily responds to visual inputs but may elect to make use of other available feedback paths such as physical motion, adopting a multi-channel control strategy. Hu- man operator identification procedures generally require a priori selection of the model structure, which can be problematic as the exact...

Interactions of Outside Visual Cues and Motion Cueing Settings in Yaw Tracking

Knowledge of how human operators’ tracking behavior is affected by simulator motion cueing settings is of great value for flight simulator design and fidelity evaluations. Previous studies have revealed strong effects of degraded motion cueing quality on human operator control behavior in compensatory tracking, but the presented visual cues in...
