Hello to everybody. I have to do a project in automatic control and I've stuck a little.The situation is this:
We have a transfer function G(s)=3750/((s+10)*(s+30)*(s+100)) and we must design a controller so that the output of the closed loop system follows the input as faster as possible. Then we need to implement the closed loop system with operation amplifiers with Vcc=12V.We have decided that the controller is 8.66*(s+10)*(s+30)/(s*(s+40)) . The problem is that the exercise also requires that with a small change in the controller if the input is a step function from 0 to 5 volts the output to go to 5 volts not as fast as possible this time (of course we want none stage to fall to saturation). We thought that we can change the gain of the controller with a variable resistor and make it smaller but the simulation with pspice gives an output of 1.6 volts but we want 5. What do we need to change?
Please answer as soon as possible
