Study and adjust sensors and actuators


Study and adjust a simple control loop:

Identify loop components: sensor, controller, actuator
Controlling variable and controlled variable concepts
Identify the system: integration constant and dead time
Determine P, I and D actions and controller parameters
Study the system’s response to interference and setpoint changes
