Lab02 - PID control Ev
Second order system with delay
ZN margin stability Ku and Tu
Simulates the closed loop using Kc, verify that osculates and osculation period equal Tu
Check the PID controller results
Design the PID controller using the step response approximation (which is a bit far from the 1st order system.) to see the results of the PID controller obtained
Check the comparison between the 2 PID controllers and comment (margin approximation is probably better , why?)
Optional: manual tune the PID controller to obtain a better response, why is better?
Check on IAE method compare with stability margin method.
Optional: a unstable system margin method do not work, system always unstable step response may possible to estimate dominant unstable pole, but PID controller response terrible ?
Optimal method no chance ?
Possible with root-locus compensation ? possible to reach a stable system ? which is the the best you can get ?
