Слайд 2Transformations of block diagram
In the case of more complicated systems,
which consists of many elements and several feedback loops it
is advisable to use the transformations of block diagrams in order to simplify them.1. In series connection:
2. Parallel connection:
3. Feedback:
4. Shifting a summing junction before an element:
5. Shifting a summing junction after an element:
6. Shifting a branching before an element:
7. Shifting a branching after an element:
Слайд 3Structure of closed-loop control systems
Example of closed-loop control system:

Слайд 5Structure of closed-loop control systems
Closed-loop control system (general block diagram):
yo (t) – reference (set point, input signal) u(t) – control
signaly(t) – controlled signal (output signal) d(t) - disturbance
ys (t) – measured controlled signal (ys (t) ≈ y(t))
e(t) - error e(t) = yo (t) - ys (t)

Output-reference response transfer function:
Output-disturbance response
transfer function:
Error-reference response transfer function:
