Subject: DC Motor PID control
I am trying to bulid a DC motor model with PID controller
I already build the model and when I tried to design the PID controller using MATLAB 2012 PID tune I got a PID controller with 4 paramters
P I D and N
with the following formula
P (1 + I(1/s) + D (N /1+N/S))
I run the simulation with the PID (tuned by MATLAB) and it gives uper results
when I used this formula P (1 + I(1/s) + D (N /1+N/S)) and implement it by myself as a model with P I D and N gains (tuned)
I got strange results
can anybody help?
why different results?
Do MATLAB uses something else not only this formula with these paramters
