Automation, Control Equipment. Test 3

What is the meaning of

The slave controller can be in any mode of operation
The slave controller can be tuned from the engine control room
The slave controller receives the set-point from the output signal of the master controller
The slave controller can be tuned by a hand carried remote controller

What is dynamic amplifying

Amplitude of output signal divided by amplitude of input signal
Amplitude of input signal divided by amplitude of output signal
Corresponding change in signals
Variable amplifying

In a PID controller we have possibility to change the setting of the Proportional band (P), the Reset time (I) and the Rate time (D). Please indicate which curve shows the typical response to change in input, if the setting of the reset time is too fast.

In a cascade control system, what is the correct mode of the slave controller during normal operation

he slave controller shall be in manual mode
The slave controller can be in any mode
The slave controller shall be in remote mode
The slave controller shall be in auto mode

In a PID controller we have possibility to change the setting of the Proportional band (P), the Reset time (1) and the Rate time (D). Please indicate which curve shows the typical response to a change in input, if the setting of the proportional band is too wide.
