Modelling of 6th order system with opamps (IC 741) and making PID controller with Op-amps only, for the particular system to make it stable and record it's response.
Additionally notes are also required for the modelling.
Software which can be used are: Pspice, Proteus, Simulink or any electronic simulation software.
P.S.: you can start with lower order system, if it's little tough and then turn to 6th order.
Hello. Usually I use LTSpice 4 for such tasks. I have a wealth of design experience. I also have Filter Solutions for filter design. I'm ready to start tomorrow night and finish by monday.
