Laplace Transforms
Laplace Transforms move time-domain functions to this domain.
What is the s-domain or Laplace-domain?
A transfer function is the ratio of an output function to this type of function.
What is input function?
What are proportional gain, integral time, and derivative time?
Stability analysis requires this type of transfer function?
What is open-loop?
LOOP-PRO uses this tuning method.
What is IMC?
The Laplace Transform of this function is 24/s.
What is 24?
A first-order plus time delay transfer function includes these three parameters.
What are process gain, process time constant, process time delay?
Increasing integral time leads to this type of response in a closed-loop system.
What is less aggressive?
A Bode Plot contains these two plots.
What are phase angle and amplitude ratio?
This control scheme contains two controllers, with one controlled by the other.
What is cascade?
Laplace Transforms convert differential equations into this type of equation.
What is an algebraic equation?
This type of transfer function only contains a gain term.
What is zero-order?
A closed-loop response plot will exhibit this if the controller is set to Proportional-only control.
What is offset?
The phase angle is equal to -180o at this value.
What is the crossover frequency?
Closed-loop stability can be determined using this by-hand method.
What is direct substitution?
This method is used to find partial fraction residues.
What is Heaviside Expansion?
The roots of the polynomial in the numerator of a transfer function are known as this.
What are zeros?
A controller is said to be in this mode if it is set to automatic.
What is closed-loop?
This tuning method utilizes stability plots.
What is Ziegler-Nichols?
A system is stable if all of its poles meet this condition.
This theorem is used to insert time delays into time-domain response functions.
What is the Real Translation Theorem?
Transfer functions can be determined through these two methods.
What are step tests and dynamic modeling?
Controllers make process input manipulations based on this measure.
What is error?
Phase angle has this type of relationship with controller gain.
What is none?
Linearization of dynamic models is based on this mathematical expansion.
