Question 1.
What is feedback linearization?
Show hintHide hint
Think about how nonlinear terms can be redefined in a system.
Question 2.
Can you name a disadvantage of Sliding Mode Control?
Show hintHide hint
Consider the properties of SMC in response to disturbances.
3Question 3.
What is the purpose of feedback linearization?
- To stabilize linear systems only
- To convert nonlinear systems to linear systems
- To introduce nonlinearities into systems
Show hintHide hint
Focus on the transformation aspect of control.
4Question 4.
True or False: Sliding Mode Control can improve robustness against disturbances.
- True
- False
Show hintHide hint
Consider how the SMC approach deals with unexpected changes.
Question 5.
Design a feedback linearization controller for a robotic arm that experiences significant friction at its joint. Describe your approach and the expected outcomes.
Show hintHide hint
Be specific about how friction alters the system response.
Question 6.
Analyze a scenario where a cart experiences lateral disturbances while moving along a track. Discuss how SMC can be applied to stabilize the motion and what modifications could be necessary to reduce chattering.
Show hintHide hint
Assess how the physical system may react to disturbances and what strategy could help.
