How to use Matlab to solve for ω for transfer function equation below:
Magnitude of | (0.001325 s + 110.4) / ( 1.872e-33 s^5 + 3.052e-24 s^4 + 7.143e-16 s^3 + 1.059e-09 s^2) | = 1
s = jω
Manual calculation shows that ω = 164.294e3*2pi
and verify ω = 164.294e3*2pi in Matlab gets abs = 1 and angle = 50.455 degress, which is correct.
However, it is very time consuming to do manual calculation.
Is there a quick way to convert transfer function in s to complex function in jω, then get the magnitude of that complex function = 1 (or other value)?
The abs function only able to get magnitude of complex function if we know ω, but not abs(complex(jω)) = 1.
