What is the static gain of a system?
The number G(0) is called the static gain of the system because it tells the ratio of the output and the input under steady state condition. If the input is constant u = u0 and the system is stable then the output will reach the steady state value y0 = G(0)u0.
What is the frequency response?
A frequency response describes the steady-state response of a system to sinusoidal inputs of varying frequencies and lets control engineers analyze and design control systems in the frequency domain. To understand why the frequency domain is important consider an acoustic guitar.
What is transfer function of a system?
In engineering, a transfer function (also known as system function or network function) of a system, sub-system, or component is a mathematical function that theoretically models the system's output for each possible input. They are widely used in electronics and control systems.
What is the transfer function formula?
Characteristic equation of a transfer function -
Here, the characteristic equation of a linear system can be obtained by equating the denominator to the polynomial of a transfer function is zero. Thus the characteristic equation of the transfer function of Eq.1 will be: an sn+a(n-1) s(n-1)+.........+a1 s+a0=0.
