Integrator transfer function
To configure the integrator for continuous time, set the Sample time property to 0. This representation is equivalent to the continuous transfer function: G ( s) = 1 s. From the preceeding transfer function, the integrator defining equations are: { x ˙ ( t) = u ( t) y ( t) = x ( t) x ( 0) = x 0, where: u is the integrator input.In general, both transfer functions have the form of an integrator with a single real zero. Adopting a somewhat neutral notation, we can write either configuration in the form s b s b F s ( ) 1 0 (4) This form is the same as the “zero plus integrator” commonly used in power supply loop compensation, in which b1 = 1 and b0 isThe transfer function, T, of an ideal integrator is 1/τs. Its phase, equal to −π/2, is independent of the frequency value, whereas the gain decreases in a proportional way with this value of ω. However, on the one hand, it is usually necessary to limit the DC gain so that the transfer function takes the shape T=k/(1+kτs). On the other ...
