No mathematical model exactly represents a No physical system. Output Modeling Model Do not confuse models with physical systems! Do systems! In this course, we may use the term “system” to In system” mean a mathematical model. A model is used for the analysis and design of model analysis design control systems. 2008/09 MECH466 : Automatic Control 5 2008/09 Transfer function MECH466 : Automatic Control 6 Impulse response A transfer function is defined by transfer Suppose that u(t) is the unit impulse function Suppose u(t) and system is at rest. Laplace transform of system output System Laplace transform of system input The output g(t) for the unit impulse input is called The g(t) impulse response. im...
