This thesis investigates a wide-bandgap silicon-carbide based IPMSM drive system, to reduce the switching loss and conduction loss, increase its efficiency, and improve its performance as well.
In order to improve the transient responses, load disturbance responses, and harmonic currents of the stator, this thesis proposes a predictive speed controller and a predictive current controller for the IPMSM drive system. Experimental results show the predictive controllers provide better performance than the PI controllers.
A digital signal processor, TMS320F28035, is used as the control center to execute the control algorithms. By using the implementing hardware and DSP programs, the adjustable speed of the proposed IPMSM drive system is from 10 r/min to 1800 r/min, which shows the adjustable speed range is 180:1. Experimental results verify the correctness and feasibility of the proposed methods, and show the predictive controllers provide satisfactory performance.
