It has a high level of elasticity to deal with different network characteristics without the need for human tuning. It has been evaluated by comparing its performance to Compound TCP (the default CCA in MS Windows), CUBIC (the default for Linux) and TCP-BBR (the default of Linux 4.9 used by Google) using the NS-2 simulator and testbed.
In data communications, flow control is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver. Flow control should be distinguished from congestion control , which is used for controlling the flow of data when congestion has actually occurred. [ 1 ]
Similarly, high-speed pulse-width modulation or delta-sigma modulation produces outputs that only assume two states, but the effective output swings through a continuous range of motion. These complications can be avoided by using a different nonlinear control design method that produces a continuous controller. In some cases, sliding-mode ...
Variable structure control (VSC) is a form of discontinuous nonlinear control. The method alters the dynamics of a nonlinear system by application of a high-frequency switching control . The state - feedback control law is not a continuous function of time; it switches from one smooth condition to another.
A basic closed loop control system, using unity negative feedback. C(s) and G(s) denote compensator and plant transfer functions, respectively. Let () and () denote the plant and controller's transfer function in a basic closed loop control system written in the Laplace domain using unity negative feedback.
Control systems can be divided into different categories depending on the number of inputs and outputs. Single-input single-output (SISO) – This is the simplest and most common type, in which one output is controlled by one control signal
The higher levels in turn control by adjusting the reference levels (goals) of the lower levels, in effect telling the lower levels what to perceive. [ 25 ] [ 33 ] While many computer demonstrations of principles have been developed, the proposed higher levels are difficult to model because too little is known about how the brain works at these ...
Two aircraft manufacturers produce commercial passenger aircraft with primary flight computers that can perform under different flight control modes. The most well-known is the system of normal , alternate , direct laws and mechanical alternate control laws of the Airbus A320 - A380 . [ 3 ]
