Beyond that, a closed loop control is developed, which adapts the roller speeds around the calculated setting point when the produced quality deviates from the desired quality.
This type of motor is characterized by a particular structure similar to that of the rotary stepper motor and it is widely used in open loop control. During the 1970s the closed loop control was introduced in stepper motor in order to increase the positioning accuracy and to reduce their sensitivity to disturbances load [1], [2].
An optimal open loop control is first obtained by using a time scaling transform [18] and the control parameterization technique [19].
Among his topics are the basics of loop control, stability criteria of a control system, operational transconductance amplifier-based compensators, shunt regulator-based compensators, and measures and design examples.
The CS series of process control modules provide PID loop control of any process without requiring a programmable logic controller.
From these results, the closed loop control algorithm is capable of reaching the target value rather quickly.
These demonstrated that carbon medium wave infra-red could achieve the required web temperature at the required line speed and that this could be effectively regulated by a loop control system.
The computer can interface with remote communications, temperature, pressure and density monitoring, process loop control, report printing and the capability of providing analog and digital outputs to remote equipment.
Closed loop control is available on most of the current technologies and is used successfully in a large number of applications.
Modular software design allows use of various closed loop control methods: PID control, classic linear or non-linear control, fuzzy logic and more, the company said.
Designed for harsh environments, it provides continuous measurements for both simple monitoring and interface to closed loop control systems.
The Q50 can be used for measurement applications, including dry-bulk level measurement, package filling, roll-diameter measurement, loop control and dimensional measurement.
