Abstract: A rotary system includes a rotor, a vector-based position sensor, and a controller executing a method to eliminate fundamental harmonic position measurement error. The sensor measures angular position of the rotor and outputs raw sine and cosine signals representative of the angular position. The raw signals have a fundamental harmonic position measurement error at the frequency of the sensor signals. The controller receives the raw signals, adaptively adds or subtracts sensor signal offsets to or from the raw signals to generate offset sine and cosine signals, calculates a corrected position of the rotor using the offset sine and cosine signals eliminating the fundamental error, and controls an action or state of the rotary system using the corrected position. The rotor may be part of an electric machine, such as in a vehicle.

Abstract: An aircraft control device calculates trajectories of multiple aircraft that is member of a flight by use of a method such as Direct Collocation with Nonlinear Programming (DCNLP), in which an optimal solution is obtained by discretizing continuous variables. Nodes indicating the trajectory are calculated and set by substituting a discretized control variable of the aircraft into an aircraft equation of motion, or by use of other methods. Instead of calculating the trajectory of the aircraft as a continuous problem, discretisation reduces the calculation amount and time required for the trajectory calculation. The aircraft control device then determines, from among trajectories satisfying constraints corresponding to the role of the aircraft, an optimal trajectory based on an evaluation value obtained by an objective function corresponding to the role. Accordingly, the aircraft control device can calculate a more optimal trajectory corresponding to the role of the aircraft in a shorter time.

In particular, only the partial movement cost Cim in the first partial link Lim is used to determine the total movement cost Ci of the designated link Li.

Abstract: A control system for resonant inertial actuators estimates operating parameters of the resonant inertial actuators based on voltage and current feedback and dynamically limits selected parameters to maintain the safe, efficient, and cost effective operation of the resonant inertial actuators. Resistance within the electrical drives for the resonant inertial actuators is estimated from the voltage and current feedback and in conjunction with the modeling of the resonant inertial actuators other operating parameters are calculated or otherwise estimated. Having regard for the responsiveness of the resonant inertial actuators to changes in command signals, the command signals are adjusted to dynamically limit the estimated parameters.

Abstract: The disclosure relates to a method for determining the accuracy of a satellite-based navigation system for a vehicle during operation on a test route. The method includes providing a light beam propagating essentially perpendicularly to the direction of travel along the test route at each of two selected measurement points on the test route. Upon detection of the light beams impacting the vehicle perpendicularly to the direction of travel, a detection of the position and the direction of travel measured by a receiver of the satellite-based navigation system is triggered by means of an optical triggering device fastened on the vehicle. Finally, an accuracy of the satellite-based navigation system is determined on the basis of the two detected positions and directions of travel and position coordinates of the two selected measurement points. The disclosure also relates to a corresponding system for determining the accuracy of a satellite-based navigation system.

Abstract: An autonomous vehicle includes interior sensors including a camera, IR camera, electro-chemical sensor, humidity sensor, and temperature sensor. Initial and final outputs of these sensors are captured for a trip conveying one or more passengers. If changes in the outputs of the sensors are detected, whether the final outputs of the sensors are acceptable may be evaluated. In some embodiments, an aggregation of the outputs is evaluated and found unacceptable even where individual outputs are acceptable. Outputs may be presented to a dispatcher to confirm that the outputs are unacceptable. If the outputs are found to be unacceptable, the vehicle may be autonomously driven to a cleaning station. Personal items may be identified in camera outputs and alerts generated in response.
