Specification:
TEMPERATURE CONTROL TRAINER (COMPUTER CONTROLLED SYSTEM)APPARATUS
Theprocess setup consists of heating tank fitted with thyristor-controlled heaterfor on line heating of the water. Water is supplied from laboratory constanthead tank and its flow can be manipulated and measured by provided Rotameter.The temperature of the heated water is sensed by RTD sensor. This measuredvariable through Temperature Transmitter is communicated to Digital IndicatingController. Error is calculated and output, accordingly, is communicated toThyristor Controlled heater to achieve the Set Point. These units along withnecessary piping are supported in a well-designed housing and are fixed on baseplate.
Experimentation:
Tostudy the open loop or manual control
Tostudy the proportional control
Tostudy the two mode (P+I) control
Tostudy the two mode (P+D) control
Tostudy the three mode (PID) control
Tostudy the tuning of controller (Open loop method) using Zeigler-Nichols method.
Tostudy the stability of the system using the BODE PLOT.
