To draw Bode diagram there are four steps:.
Sketch Bode plot of each factor, and 2. Note: By looking at a Bode diagram you should be able to determine the relative order of the system, its break frequency, and DC (steady-state) gain.
The high frequency asymptote of the gain is K ( ω τ) n.
4, the DC motor transfer function is described as: G(s) = K (s + 1 / τe)(s + 1 / τm) Then, system poles are located at: s1 = − 1 τm and s2 = − 1 τe, where τe and τm represent the electrical and mechanical time constants of the motor. Note: By looking at a Bode diagram you should be able to determine the relative order of the system, its break frequency, and DC (steady-state) gain. (1) 2 jω We call ω = 1 , the break point.

. A: Bode plots are a actually a set of graphs which show the frequency response of a system. .
The frequency response, taken for , has a DC amplitude of:. 5 1 Bode.
BODE DIAGRAMSBode diagrams constitute a convenient way to represent the frequency response characteristics of a system. 1.
The standard block diagram of a single-input single-output (SISO) feedback control system (Figure 4. The approach can be used to sketch Bode plots for overdamped second-order systems (which can be expressed as a connection of two first-order systems).
00000001 : 1. This process should also be reversible, i. 2.
frequency plot of a Bode diagram, we superposition all the lines of the different terms on the same plot. . 2 Bode Plots. 5 ± j 6. The standard block diagram of a single-input single-output (SISO) feedback control system (Figure 4. Craig 2 • Time delays or dead-times (DT’s) between inputs and outputs are very common in industrial processes, engineering systems, economical, and biological systems.
