Lecture 3 Flashcards
What is the reference input in a controller?
the desired value of the measured output at time k
What does the model building phase do in the push-button methodology
In the push-button methodology for model building, the process typically involves creating a model in stages, starting with basic elements and gradually adding complexity. This phased approach allows for better understanding and management of the model’s components before moving on to more intricate features.
In a feedback control loop, what does the control error represent? A) The difference between the desired output and the actual output
B) The control signal sent to the target system
C) The disturbances affecting the system
D) The measured output at time k
A) The difference between the desired output and the actual output
What is the purpose of the Proportional-Integral-Derivative (PID) controller? A) To minimize the control error over time
