Impact Analysis of DC Voltage Control Reference on Stability in DC Systems as Nonlinear Time-Invariant System
This paper focuses on the impact of DC voltage control reference on the stability of nonlinear time-invariant DC power supply systems. By analyzing system principles and control parameters, the upper and lower limit of DC voltage reference ensuring stability is derived. A proportional function-based voltage transfer function is constructed, and Nyquist plots are employed to analyze stability conditions, clarifying how key parameters affect stability. Simulation results validate the correctness of the analysis and calculations, providing a reference for parameter determination in DC systems.
