Name three major advantages of closed loop control when compared to open loop control - correct
answer ✔✔1. Able to reduce system's sensitivity to external disturbances
2. changes in feedback signal can be reduced by the controller
3. good accuracy and high speed of response
Name two disadvantages of closed-loop control - correct answer ✔✔1. Usually cost more than open
loop controller
2. Sensitivity to disturbances; can lead to instability if this sensitivity is too high
Use of Laplace Transforms is limited to _________Systems - correct answer ✔✔Linear Time Invariant
Systems
Give one use of the Final Value theorem in control system analysis - correct answer ✔✔rotational
applications
Give one use of Inverse Laplace Transforms in system dynamics - correct answer ✔✔determines steady-
state value of a system
Define the term 'Transfer function' for describing the dynamics of a system - correct answer ✔✔the ratio
of the laplace transform of the output variable to the laplace transform of the input variable
Transfer functions of a system are governed by __________ and __________ of the system. - correct
answer ✔✔Input and Output
Force produced by a spring is proportional to its _______ - correct answer ✔✔its displacement
