TL;DR: In this paper, a discontinuous projection-based adaptive robust controller (ARC) is proposed for the swing motion control of a single-rod hydraulic actuator with constant unknown inertia load, which takes into account not only the effect of parameter variations coming from the inertia load and various hydraulic parameters, but also the effects of hard to model nonlinearities such as uncompensated friction forces and external disturbances.

TL;DR: In this article, a direct writing method for gallium-indium alloys is presented, where the relationship between nozzle inner diameter, standoff distance, flow rate, and the resulting trace geometry are demonstrated.

TL;DR: In this paper, a discontinuous projection based adaptive robust controller (ARC) is proposed for the swing motion control of a single-rod hydraulic actuator, which is able to take into account not only the effect of parameter variations coming from the inertia load and various hydraulic parameters but also the effects of hard-to-model nonlinearities such as uncompensated friction forces and external disturbances.

TL;DR: Experimental results of the proposed control law on the motion axes of a machining center, Matsuura MC510V, showed significant improvement of the contouring accuracy compared to the existing servo controller as well as the successful decoupling between the tangential dynamics and the normal (contouring) dynamics for feedrate up to 6 m/min (4 in/s).

TL;DR: In this paper, an adaptive-passive vibration absorber using shape memory alloys (SMA) was constructed and tested using spring elements composed of three pairs of SMA wires and one pair of steel wires.
