In this paper, we apply Machine Learning methods to improve the aircraft climb prediction in the context of groundbased applications. Mass and speed intent are key parameters for climb prediction. As they are considered as competitive parameters by many airlines, they are currently not available to groundbased trajectory predictors. Consequently, most predictors today use reference parameters t...

In this work, a second-order sliding mode control algorithm is proposed for variable speed laboratory size DC generator wind turbine experiment system in order to track a speed profile and operate the wind turbine at maximum power extraction. The turbine torque, which varies with the wind speed, is considered as an unknown disturbance and rejected by the sliding mode strategy. The sliding mode ...

We consider the speed planning problem for a robotic manipulator. In particular, we present an algorithm for finding the time-optimal speed law along an assigned path that satisfies velocity and acceleration constraints and respects the maximum forces and torques allowed by the actuators. The addressed optimization problem is a finite dimensional reformulation of the continuous-time speed optim...

APPROACH Consider the simulated SW06 scenario with a “true” bottom consisting of 3 sediment layers (to­ taling 22m in depth extent – a medium thickness) where all three sediment layers are each defined by a linear sound-speed profile (and constant densities) all over a half-space (constant sound-speed and density) as seen in Fig. 1. For the inversion processing we shall (as in earlier work) ass...

Robots are increasingly performing human work as manufacturing is automated. Accordingly, the use of precision speed reducers has become essential for achieving precise control of the robot arm position. Curved tooth profiles, such as cycloid or involute tooth profiles, are generally used in precision speed reducers. Speed reducers with cycloid tooth profiles, which enable high precision contro...

In this paper, the Cramér Rao bound (CRB) for range estimate between two underwater nodes is calculated. The nodes are equipped with Conductivity-Temperature-Density (CTD) sensors to measure their depths, and the sound speed at different depths, and an acoustic modem to measure their mutual time of flight. The measurement noise is assumed to be Gaussian distributed. We show how much the CRB get...

Electrochemical milling using a delta-type parallel mechanism is proposed to achieve high-speed translation of the tool electrode, which known improve surface finish. Experimental results machining groove show that roughness decreases with increasing speed electrode. Moreover, it found electrode effective at preventing electrical discharge damage both and workpiece. Large areas can be machined ...

We consider optimizing a truck's choice of path and speed profile to minimise fuel consumption, exploiting real-time predictive information on dynamically varying traffic conditions. Time-varying conditions provide particular challenges, both from network-level interactions (e.g. slowing consume more locally may be beneficial avoid congested periods downstream) link-level phenomena interaction ...
