摘要：
A six-pulse noncirculating-current cycloconverter-fed synchronous motor with stator-flux-oriented vector control for high-power and low-speed applications is discussed here, Vector control is achieved by stator flux estimation through a novel closed-loop reduced-order observer exhibiting stable speed regulation. Variable displacement factor operation is incorporated to keep both the system current continuous and the system utilization optimum. A simple method is used in designing the controller for armature current regulation with good performance. A generalized digital simulation of the drive system is made, and the simulation results are validated by a low-cost laboratory implementation of the drive with a 386DX PC-based system with 80387 floating point support.
