Lecture 11: 29th April, 2020. ONLINE LESSON.

Part 1:
–Â Practical session:

Part 2:
–Â WeÂ studied lesson 3.2 (design of state observers) and we did a complete example.
– You can find next the recording of the videoconference and the materials generated during it.

Please remind that you can do the final exercises of the subject (available on the blog), which can add up to 1 additional point to your final mark (continuous evaluation). You can solve these three exercises either individually or in teams up to 3 students. The deadline is June 3.

Lecture 12: 6th May, 2020. ONLINE LESSON.

Part 1:
–Â Practical session:

Part 2:
– We completed the final example of lesson 3.2, analyzing the possibility of cancelling zeros that have influence on the dynamic response.
– We did exercise 10 of lesson 3.1. (controlling a system which is not controllable and not observable).
– WeÂ studied lesson 3.3 (design of control systems to track a reference).
You can find next the recording of the videoconference and the materials generated during it.

Lecture 13: 13th May, 2020. ONLINE LESSON.

Part 1:
– WeÂ did the final example of lesson 3.3,Â (design of an integral controller, state feedback and observer).
– WeÂ introduced the control of MIMO systems.
1. First we studied that there are different possibilities to share the energy of the inputs between the state variables. Each possibility leads to a specific CCF of the original system.
2. We started to solve an example about how to set the dynamics of a MIMO system by using a continuous-time controller (state feedback).

You can find next the recording of the videoconference and the materials generated during it.

Part 2:
–Â Practical session:

Lecture 14: 20th May, 2020. ONLINE LESSON.

Part 1:
– We continued the study of MIMO systems:
1.Â We finished example 1: Design of the state feedback. In it, we studied that there are different possibilities to build the matrix A of the controlled system in CCF. It is recommendable to develop and check some of them, and retain the solution with the most balanced control inputs.
2. WeÂ did example 2: Design ofÂ a MIMO observer.
3. We did example 3: Simultaneous design of the state feedback and the integral controller in a MIMO system.

You can find next the recording of the videoconference and the materials generated during it.

Finally, as I told, you’ll find here an example ofÂ Midterm Exam 2.

Part 2:
