Lecture 8.1 Frequency Domain Design Goals:
• Describe the use of frequency domain performance specifications • Show how to use “loop shaping” to achieve a performance specification • Work through a detailed example of a control design problem
J = 0.0475;m = 1.5; r = 0.25; g = 10; d = 0.001; l = 0.05;
Sisotool design Example1:
J = 0.0475;m = 1.5; r = 0.25; g = 10; d = 0.001; l = 0.05; % Transfer function for pitch dfsys = tf([r], [J d m*g*l]); sisotool(dfsys)
Sisotool design Example 2:
Given transfer function: 400 G = -------------------s^3 + 30 s^2 + 200 s Performance specification: damping ratio=0.5; natural frequency=13.
G=tf(400,[1 30 200 0]) sisotool(G)
