Control Panels Menu
This menu shows the available interactive panels that are configured by the
. A panel is a
control unit that allows a specific control task or acquisition of sensor data. There are 5 types of control panels:
•
Single Stat:
an input-only controller for displaying sensor measurements
•
Switch
: an ON/OFF output-only (open-loop) controller
•
Slider
: a range output-only (open-loop) controller
•
ON-OFF controller:
a closed-loop controller with ON/OFF (bang-bang) control algorithm
•
PID Controller:
a closed-loop controller with PID control algorithm
In the example picture below:
The
C2H4 PID
panel is a
PID controller
. As a closed-loop controller, it requires sensors for input and actuators for
driving output in the system. In this case, the sensor feedback is ethylene measurement from the F901B Sensor and
the actuator is the ethylene generator.
The
Environment
panel is a
Single-Stat
controller, which periodically acquires additional sensor data from the F901B
sensor.
