I think that state state space is effective by multiple input/output systems, but you have a system with only one input ( F ), thus a classical model is more effective here.but I'm missing one equation to make a state space model.
Say you have a closed loop (negative feed back).how will I draw a loop to apply mason rule
Perhaps not too important for solving this task - but for the sake of clarity I like to mention that the given formula for the closed-loop transfer function is known as Blacks formula; Mason`s rule is different from that.Say you have a closed loop (negative feed back).
Say that the forward path has the transfer function: A(s) and that the backward path has the transfer function: B(s), then Masons rule says that the transfer function for the loop as a whole =
A(s) / ( 1 + A(s)*B(s) ) . . . . ( It's easy to prove ).
If the feedback is positive, you simply change the "+" to a "-".
x2 is the velocity(?)/position(?) in the diagram shown in #2. This diagram is just a copy from one of the links in #1. I don't know, I have assumed it's an output, and that F is the input.* What is x2? Input or output (according to your block diagram)?
* Where is c1 in the diagram?
