## Control Engg: Assignment 12 Solutions

Dear Students,

Solutions for Assignment 12 have been released. Kindly check in Module 12 section to view and download the solution document.

## Control Engineering: Clarification regarding lecture 53 on controllability and pole placement

Hi,

Please note the following change in lecture 53 (module 12) on controllability and pole placement:
At 00:40:52, the correct determinant formula is  $|sI-A+BK|=|\begin{bmatrix}s&-1&0\\0&s&-1\\a_3+K_1&a_2+K_2&s+a_1+K_3\end{bmatrix}|\\ =s^3+(a_1+K_3)s^2+(a_2+K_2)s+(a_3+K_1)=0$
so that
$K_1=\alpha_3-a_3,\ K_2=\alpha_2-a_2,\ K_3=\alpha_1-a_1$
Apologies for the mistake.

## Control engineering: Clarification regarding Assignment 12

Hi,

Please note the following changes in questions 3 and 8 of assignment 12:
Question 3: Is the system in question 1 stable? (ignore the phrase 'closed loop').
Question 8: Please compute the open loop poles of the system for the given parameter values. It is incorrectly typed as 'closed loop poles' in the question.

Kindly note the above change before submitting your answers for assignment 12. Sorry for any inconvenience.
