The term of relative degree is used a lot in books of control systems. I need some explaining to understand the useful and effect of the relative degree on analysis and design the control system. For example the following transfer function: $$G(s)=\frac{s+1}{s^2+s+1}$$ has a relative degree one, another example the relative degree two or more. I need to know why it is important and where I have to take the relative degree in account when I design a control system.
