Chapter 1OverviewChapter 1Overview

1-1 General1-1 General

The Fuzzy Logic plus PID microprocessor-based controller series,

incorporate a bright, easy to read 4-digit LEDdisplay,indicating

process value or set point value. The FuzzyLogic technology

enables a process to reach a predetermined set point in the

shortest time, with the minimum of overshoot duringpower-up or

external load disturbance.

The TC/PC 24 is a 1/32 DIN sizepanel mount controller. These units

are powered by 11-26 or 90-250 VDC/VAC supply, incorporating a

2 amp control relay output as standard. Thesecond output can be

used as cooling control, an alarm or dwell timer. There are

six types of alarm plus a dwell timer can beconfigured for the

second output.The units are fully programmable for PT100 and

thermocouple types J,K, T, E, B, R, S, N, Lwith no need to modify the

unit. The input signal is digitized by using a18-bit Ato D converter.

Its fast sampling rate allows the unit to control fastprocesses.

By using proprietary Fuzzy modified PID technology, the control

loop will minimize the overshoot and undershoot in a shortest

time. The following diagram is a comparisonof results with and

without Fuzzy technology.

High AccuracyHigh Accuracy

The series are manufactured with custom designedASIC(Application

Specific Integrated Circuit ) technology which contains a 18-bitA to

D converter for high resolution measurement ( true 0.1BF resolution

for thermocouple and PT100 ) and a 15-bit Dto Aconverter for linear

current or voltage control output. TheASIC technology provides

improved operating performance, low cost, enhanced reliability and

higher density.

Fast Sampling RateFast Sampling Rate

The sampling rate of the input Ato D converter reaches 5 times/second.

The fast sampling rate allows this series to control fast processes.

Fuzzy ControlFuzzy Control

The function of Fuzzy control is to adjust PID parameters from time to

time in order to make manipulation output value more flexible and

adaptive to various processes. The results is to enable a process to

reach a predetermined set point in the shortest time, with the minimum

of overshoot and undershoot during power-up or external load

disturbance.

Auto-tuneAuto-tune

The auto-tune function allows the user to simplifyinitial setup for a

new system. Aclever algorithm is provided to obtain an optimal set

of control parameters for the process, and itcan be applied either as

the process is warming up ( cold start )or as the process has been

in steady state ( warm start ).

Lockout ProtectionLockout Protection

According to actual security requirement, one of four lockoutlevels

can be selected to prevent the unit from beingchanged abnormally.

Bumpless TransferBumpless Transfer

Bumpless transfer allows the controller to continue to control by

using its previous value as the sensor breaks. Hence, theprocess

can be well controlled temporarily as if the sensoris normal.

Soft-start RampSoft-start Ramp

The ramping function is performed during power up as well as any

time the set point is changed. It can be ramping up or ramping

down. The process value will reach the set point with a predetermined

constant rate.

Digital FilterDigital Filter

A first order low pass filter with a programmable time constant is used

to improve the stability of process value. This is particularly useful in

certain application where the process value is too unstable to be read.
