STABILITY ANALYSIS OF A CLOSED MOTOR-GEAR-ALTERNATOR (MGA) SYSTEM USING NYQUIST TECHNIQUE |

In the design of control circuits, the stability of circuit systems, which includes power efficiency, linearity, and stability over a wide range of power input and impedance, is critical. The Motor-Gear-Alternator (MGA) circuit is a common system that has gotten a lot of interest because of its potential industrial uses. The MGA system's stability, on the other hand, is yet to be determined. Various loops have been created and stability analytical approaches have been devised to determine the stability of MGA. Closed loops of MGA circuits were studied and evaluated using the Nyquist and bifurcation criteria that had already been established. According to the Nyquist criterion, the total number of counterclockwise encirclements of -1 was zero, and the number of poles of GH(s) characterised by positive real parts was zero. The close-loop of the MGA system is stable when using Cauchy's and Nyquist stability functions.
