ommon motion systems use three types of control methods. They are position control, velocity control and torque control.
The majority of Newport’s motion systems use position control. This type of control moves the load from one known fixed position to another known fixed position. Feedback, or closed-loop positioning, is important for precise positioning.
Velocity control moves the load continuously for a certain time interval or moves the load from one place to another at a prescribed velocity. Newport’s systems use both encoder and tachometer feedback to regulate velocity.
Torque control measures the current applied to a motor with a known torque coefficient in order to develop a known constant torque. Newport’s motion systems do not employ this method of control.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

Textile(Loom)
1. Introduction
- Driving of yarn drum of loom should be controlled
in line with main motor. Because the conventional
system uses reduction gear, gearing ratio should be
changed if the product type is altered. Therefore, we
decided to control tension using inverter.
- Field : Textile/loom
- Type : iS5/iS7
3. Main function
- Linkage control: Speed of main motor that releases the
spool should be controlled in line with line speed of the
drum ⇒Rpm of main motor (for spool driving) is used
as feedback for main speed control.
- PID control: Feedback tension control

- Traverse operation is performed using traverse function
of APP Group, which is characteristic of iS5
- Conventionally, traverse operation was performed using
inverter’s up-down operation and FDT function. However,
it required additional volume and contact points.
- When winding yarns, it is necessary to guide the yarns
with traverse.
- By traverse operation, the drum’s rpm is altered
periodically, so that the yarns do not cluster locally
(ribbon effect) or cut off.

2. Process & system configuration
1. Introduction 3. Main function
- Maximum line speed is 200m/m, and 10V main speed control
is input.
- Unwinder: Because minimum diameter of roll is 100Φ and the
gearing ratio is 30:46,40:132,30:24, i.e. 4.048:1, the
maximum motor speed is
(200/0.1π)(132/40)(46/30)(24/30)=2577rpm. Also,
because maximum diameter of the initial material is 1500Φ,
motor speed at the maximum line speed becomes
(200/1.5π)(132/4046/30)(24/30)=172rpm. That is, 172 ~
2577 rpm should be maintained at the maximum line speed.
- Slitting bridle: Because minimum diameter of roll is 114Φ and
the gearing ratio is 24:44,21:44, i.e. 3.841:1, the maximum
motor speed becomes (200/0.1π)(44/21)(44/24)=2145 rpm.
- Rewinder : Because minimum diameter of roll is 190Φ and the
gearing ratio is 30:46,1:5, i.e. 7.667:1, the maximum motor
speed becomes (200/0.1π)(46/30)(5/1)=2569rpm. And, at
the maximum diameter of 1200Φ, the motor speed becomes
(200/1.2π)(46/30)(5/1)=407rpm.
- The rewinder uses torque minor loop mode in iV5 winder
version.
- The unwinder uses iV5 winder version with variable external
PI speed control. The Looper position data is linked with front
slitting bridle operation.

- Field: Pump
- Type: SV-iP5A
- To maintain constant pressure, load (fueling amount)
is controlled by inverter in order - PID control
⇒ 4~20㎃ of pressure signal is transferred to DCS,
and DCS sends PID output for inverter control.
- Because the motor was for medium-voltage (6,600V),
UP/DOWN transformer was used to control low
voltage inverter (440V).
⇒ Inverter input was decreased from 6,600V to 440V.
Then, inverter output was increased from 440V to
6,600V because the motor was for 6600V.
⇒ Heat resistance is important when selecting the
