Question 1.
What does LQR stand for?
Show hintHide hint
Think about the names of mathematical models used in this control method.
Question 2.
What is the role of the weighting matrix Q in the cost function?
Show hintHide hint
Consider what each part of the cost function represents.
3Question 3.
What is the primary goal of LQR?
- Maximize state deviation
- Minimize a cost function
- Reduce computational load
Show hintHide hint
Think about what makes a control system effective.
4Question 4.
True or False: The matrix R in the LQR cost function represents the importance of minimizing control effort.
- True
- False
Show hintHide hint
Reflect on the balance between application and performance.
Question 5.
You have a robotic arm designed to pick objects of various weights without tipping over. If you were to apply LQR here, how would you adjust the matrices Q and R?
Show hintHide hint
Consider the implications of weights and stability in control.
Question 6.
Design a scenario where applying LQR could lead to excessive oscillations. What matrix adjustments might cause this effect?
Show hintHide hint
Think about the implications of aggressive control responses.
