The temperature in the chamber is controlled by regulating the air flow rate supplied by the fan and heater system. The actual chamber temperature is measured by the sensor and fedback to the controller. Due to heat loss to environment, the controlled system is subjected to disturbance.
The rapid-prototyping of the control system by using ATRON® software enables the students to both observe the desired, actual, error and actuator control signals and tune the controller parameters on-the-fly. For the purpose of record and off-line observation, signals can be traced back in time.
Simulations are provided using third- party software such as MATLAB® and LabVIEW.
