Stabilization Control

A polarization stabilization control system based on digital signal processor (DSP) is proposed in this paper. The system uses low frequency radio frequency (RF) power as control signal for polarization stabilization, and it does not need high-speed circuit to track fast polarization change. Modified particle swarm optimization algorithm is utilized and the effectiveness of polarization stabilization control is experimentally verified.

Compared with traditional three-phase motors, six-phase induction motors due to their high reliabilities and low DC side voltages can achieve high power drives using devices with lower voltage level. In this paper, it analyzes the research status of six-phase induction motors, introduces the winding structures of six-phase induction motors, and finally designs the vector control system for six-phase induction motors taking the Digital Signal Processor (DSP) as the core. It introduces DSP circuit implementations, emphasizes to describe software structures of the control system, and proposes a detailed software flow chart.
