**Bode Diagram (2)**Hany Ferdinando Dept. of Electrical Engineering Petra Christian University**General Overview**• This section discusses the relationship between system type and the log-magnitude curve • How to determine the static position, static velocity and static acceleration error constants • Bode in Matlab is also explained**System type & Log-magnitude**• The type of the system determines the slope of the log-magnitude curve at low freq. • The information of the existence and magnitude of the steady-state error of a control system to a given input can be determined from the observation of the low freq. region of log-magnitude curve**System type N**• Type 0 has static position error constants • Type 1 has static velocity error constants • Type 2 has static acceleration error constants System type N is defined as the following G(s)**Bode diagram in Matlab**Function [mag,phase,w] = bode(num,den) is used to plot Bode diagram in Matlab. The num and den are numerator and denominator of the G(s) respectively. One also uses function [mag,phase,w] = bode(A,B,C,D). This function directly plots both log-magnitude and phase. The log-magnitude is on the upper side of the diagram.**Next…**The Bode diagram has been discussed here, the next topic is Phase and Gain Margin. Several important points will be discussed as well Please prepare yourself by reading the book!
