This paper contributes a distributed packet controller which reduces queueing to a single stage in two-stage packet switches. Software and neural network based controllers are described. Simulations under a range of traffic conditions for a 1024x1024 switch size shows the simplest architecture has the best performance.

a paper-pot transplanter was designed, developed and evaluated in the field by transplanting sugar beet seedlings grown in paper pots. a ground-driven counter wheel equipped with an infra-red sensor measures the traveled distance and sends the corresponding signals to a micro-controller. a step motor controlled by the micro-controller turns the driving shaft of the paper-pot metering mechanism ...

many real time processes have complex, uncertain and nonlinear dynamics. boilers are nonlinear, time varying, multi-input multi-output (mimo) systems, whose states generally vary with operating conditions. the major problem in controlling that system is that its drum water pressure and steam flow dynamics include an integrator that results a critically stable behavior. conventional controller p...

where p is the controller parameter, J is the gradient, k is the iteration number, R is a positive definite matrix and γ is the step size. In this paper, a data-driven control strategy is proposed to synthetically build the control system of a 6-DOF ultra-precision dual-stroke stage. The stage, namely reticle stage which is a critical lithographic component, moves the pattern in synchronizatio...

An industrial linear stage is a device that commonly used in robotics. To be precise, an electro-mechanical system includes motor, electronics, flexible coupling, gear, ball screw, and precision bearing. A tight fit can provide better but also generates difficult-to-model friction highly nonlinear asymmetrical. Herein, this paper proposes advanced trajectory controller based on digital twin fra...
