Comparative analysis reveals the frequency limits of various demodulator types in phase-lock motor drives, indicating potential for low-speed operation.
The article is devoted to assessing the possibility of expanding the operating range of phase-lock motor drive in the low shaft speed area. The analog and digital control system models of motor drive in Matlab software are proposed. The research of proposed models is obtained by using phase plain method. Based on a comparative analysis of the simulation results, the lower frequency limit for using different demodulator types and research methods of phase-lock loop is determined.
