Abstract :

LQG controller is also fundamental to the optimal perturbation control of non-linear systems .This paper presents a Linear-Quadratic Gaussian method of synthesis with compensator c to find poles and zeros in case of Niguist plot criteria. Here we find dynamic values of poles and zeros for type real pole, integrator and complex and later we determine values of location, damping and frequency to see the effect of poles and zeros on Niguist plot criteria. The value of frequency is maximum in real pole i.e. 42.8 at location -42.8 at damping value 1.The value of poles and zeros for type complex are lowest at location -0.0526 +/- at for frequency 2.74. at damping value 0.0192.
