A trajectory control system is proposed in this paper to solve the nonlinear, nonaffine, redundant, and coupled control problems existing in a UAV, which adopts direct force control technique.
In order to enable the onboard trajectory control, we add the following three objectives to the method.

Following the general principles exposed above, the simulation and cell workspace analysis were performed, together with Denavit-Hartenberg parameters identification, kinematic modeling of the system and Jacobian matrix formulation, followed by speed and trajectory control calculations.
This version of the T-MAX 5 low profile direct drive rotary servo positioning stage is able to deliver higher load capacity and improved trajectory control. The device is driven by a brushless servo torque motor with an integrated high resolution rotary encoder system and offers a 135-mm hub diameter platform that provides smooth, low friction rotary motion with 360[degrees] continuous travel over a large speed range with low hysteresis, noise, and vibration.
Thales is responsible for the landing system per se, the rotorcraft system as well as for the trajectory control system, while DCNS is in charge of 'ship motion prediction', deck landing strategy and for the system needed to secure the aircraft on the deck.
It takes a lot of golf ball control, a lot of trajectory control and imagination as well.
I didn't have the trajectory control that I do now and certainly didn't have the 10 years' experience of playing out on the Tour.
The device coordinates transformation for active trajectory control. In addition, a high-bandwidth analog command interface is 0 to 10 V.
Studies in stroke patients have demonstrated deficiencies in the ipsilesional arm that reflect these distinctions; patients with right-hemisphere damage tend to show deficits in positional accuracy, and patients with left-hemisphere damage show deficits in trajectory control. Such deficits have been shown to impede functional performance; yet patients with severe dominant-side hemiplegia must often use the nondominant arm as the primary manipulator for activities of daily living.
