As an engineer who has taken this course as a refresher, I found Dr. Pao's lectures to be excellent, clear and she presented exactly what I needed. The assignments were challenging (Matlab helps). The last assignment present a graph output of a step function where the amplitude of the step was 2. If one measures (I did so precisely with a mm ruler on a blown up image) the rise time, the peak time and the time to 1% steady state, one ends up with 3 very different values for the natural frequency of the system. This leads to confusion and varying result. This question could be replaced with something that renders consistent results.

Coursera did not recognize this class as a Coursera-plus class even though they advertised as such. Took 3 weeks to resolve. The following on class listed at complete "Frequency Domain" links do not lead anywhere. If Routh stability matrix is taught, should show how to use symbolic computer programs to calculate. Notes not provide and when presenting math equations instructor moves to fast to copy. This is only true control systems course I could find on Coursera. 4-star course, 1-star Coursera --> 3 stars.

Fairly good class. Students with experience in diff eqs should find it challenging. I would recommend creating extra material in using software like Mathematica or Matlab to help solve problems.

Great introduction to understanding how control theory works. Not too easy or too difficult. However, this course stops at proportional control, so there is no analysis of PID control. This is supposed to be the first of 3 courses, but only the first is available.

A great introduction to Control Theory for someone with a fair amount of mathematical / engineering background.

very good course , I am really looking forward to more courses like this one

Thanks to dr Lucy pao never seen a teacher like him

The most amazing and useful material i could find

Greate course and great teacher!

Best professor ever

Very good course

Excellent course

Good enough

Fantastic!

Good one

Good

Good

in the course, some questions were hard to understand. For future courses if possible, add conceptual hints for solving the problems.

the course is very good but we need complete all chapter of the reference

good
