Quiz on Automatic Control Systems

What is the primary role of an Automatic Control System (SRA)?

• To replace human intervention in production processes

• To increase the speed of manual operations

• To reduce the cost of production

• To eliminate the need for technology

Which of the following is NOT a criterion for classifying SRAs?

• By the nature of the input signal

• By the number of control loops

• By the color of the components

• By the speed of response to input signals

What type of signal is a unit step signal?

• A signal that oscillates between two values

• A signal that increases linearly over time

• A signal that is zero until a certain point in time

• A signal that remains constant over time

What does the term 'steady-state error' refer to in an SRA?

• The error that occurs during the transient response

• The difference between the desired output and the actual output in steady conditions

• The maximum deviation of the output from the setpoint

• The time taken for the system to stabilize

Which component of an SRA compares the output with a reference value?

• Transducer

• Regulator

• Execution element

• Comparison element

What is the primary function of a transducer?

• To store electrical energy

• To convert one form of energy into another

• To amplify electrical signals

• To measure temperature only

Which type of transducer is used for measuring pressure?

• Elastic transducer

• Inductive transducer

• Capacitive transducer

• Resistive transducer

What does a piezoelectric transducer primarily measure?

• Pressure variations

• Temperature changes

• Fluid flow

• Mechanical stress

Which of the following is a characteristic of thermocouples?

• They measure pressure directly

• They generate a voltage based on temperature difference

• They are only used in liquid measurements

• They require a power source to operate

What is the role of an adapter in a transducer system?

• To measure the input signal

• To increase the voltage output

• To provide mechanical support

• To convert the output signal to a standardized format
