How to find the transfer function of a system
In control engineering and control theory the transfer function of a system is a very common concept. A transfer function is determined using Laplace transform and plays a vital role in the development of the automatic control systems theory. By the end of this tutorial, the reader should know: how to find the transfer function of a SISO system starting from the ordinary differential equation how to simulate a transfer function in an Xcos block diagram how to simulated a transfer function using Scilab dedicated functions A system can be defined as a mathematical relationship between the input, output and the states of a system. In control theory, a system is represented a a rectangle with an input and output. where: u(t) – input y(t) – output Both input and output are variable in time. A system with only one input and output is called SISO (...
