Root locus with complex roots
WebThe root-locus is the locus of points where roots of the characteristic equation can be found as a single parameter is varied from zero to infinity. The characteristic equation of our unity-feedback system with simple proportional gain, , is: (11) WebThe root locus of the trasfer function G with some random value for K, let's say K = 1 (it is almost always good to start with the value 1 as starting point since it is like adding no …

Web6 Oct 2024 · If the equation has real-valued coefficients, the complex roots will always come in conjugate pairs. Complex conjugates share the same real-valued part and have opposite signs in their complex-valued (or imaginary) parts: a ± b i WebFrom root-locus criteria, pole angle can be reduced by the addition of a real pole at a lower frequency (Fig. 6.33a).As the pole increases in frequency due to dc loop gain K, the complex pole radius (ω n) decreases, but so does the pole angle ϕ.This decrease in ϕ is slight in a narrow range of K, making this a marginally useful technique.
