Feedback Control Systems Review of Laplace Transforms Engr. Lancer Andre T. Mendoza PRESENTED BY
Back to Agenda The Laplace Transform Used to study the complete response characteristics of feedback system, including the transient response Define the Laplace transform of f t , denoted by L f t = F s , as a function of the complex variables s = σ1 + jω, where F s = න 0− ∞ f t e −stdt
Back to Agenda The Laplace Transform Unilateral (one-sided) Laplace Transform Which uses 0 as the lower limit of intefration A function f(t) will have a Laplace transform if it is exponential order, whichmeans that there exists a real number σ1 such that lim t→∞ f t e −σ1t = 0
