Homework 4
Question 1
Describe briefly the dynamic characteristics of the PI controller, PD controller, and PID
controller.
Question 2
Consider the system shown in Figure 1.This is a PID control of a second-order plant
G(s). Assume that disturbances D(s)

Homework 2
1. Dynamic systems
Give three examples of dynamic systems, and for each system, identify at least one input
variable and at least one output variable.
2. Mathematical block diagrams

Learning outcomes
Determine possible control objectives, input variables
(manipulated and disturbance) and output variables
Assess the importance

Direct Synthesis method
For the feedback control loop above the overall transfer functions between
the output Y and the set point & disturbance are:
Note that for the set point transfer function, we can
manipulate it to give:
We can get this type of respo
