Stability Analysis of a Motor-Gear-Alternator (MGA) System Using Bode Plot Technique

Koech and the associates designed a Motor-Gear-Alternator (MGA) model and identified the effective parameters of that model. Nonetheless, the stability of the model to determine its applicability is still missing. In this paper, the author attempted to design a stable for Motor-Gear Alternator (MGA) system using Bode plots criterion. The goal was to develop a system that could perform its design and intended functions without any interruptions. Simulation showed that the system is stable for 1 ≤ Gear ratio ≤ 7 and the excess voltage is achieved when the Gear ratio > 3. Moreover, when the Gear ratio is three, the system is stable with good response. This research has contributed to the field of system modeling, system identification and system stability analysis.
