Servomechanisms Flashcards
What is the purpose of an Input Transducer?
Converts one form of energy into another and creates the initial error signal.
What is the purpose of an Amplifier?
Amplifies the error signal to a size large enough to drive the motor.
What is the purpose of a Motor?
Moves the load to the new position.
What is the purpose of a Load?
Moves to a new position determined by the motor.
What must be added to convert to a closed loop system?
Negative feedback.
What is the purpose of an Error Detector?
Provides a back off signal to oppose the input signal.
What is the purpose of an Output Transducer?
Adds the input and output transducer signals together to provide the total error signal.
What are the disadvantages of a Closed loop system?
More expensive, complex, and slower response time.
What are examples of aircraft closed loop control systems?
Control Surface, Throttle Control, Braking Systems, Temperature Control, Heated Windscreen.
What are the Servomechanism classification conditions?
Error actuated, Power amplification, Negative feedback, Continuous operation.
What happens if an E and I bar drops to the right?
If the bar moves closer to a secondary coil, a greater voltage will be induced in that side, creating a difference between the outputs that is proportional to direction and amount of movement.
