hello,
i want to implement a digital controller C(z) in arduino uno( transfer function at z domain ) in pursose to controlle the plant G(s) =3750/[(s+10)(s+30)(s+100)). i have implemented G(s) with electronis(op-amps,capacitors and resistances). i want to realize C(z) at arduino uno.The input at arduino is the error signal(REFERENCE-OUTPUT of G ) and the output of C(z) is inpute at G(s).finally i wil have a closed loop system with negative unit feedback.REFERENCE INPUT=UNIT STEP SIGNAL (1 VOLT).
MY PROBLEM IS how i use PWM AND FILTERS in place of DAC???
I want help.
thank you
