Abstract

A novel approach for primary current vector control of a current-source inverter induction motor (CSI-IM) drive with an improved estimation of slip angular frequency is described. Accurate digital control of the current vector orientation is achieved. Advanced software control logic provides the drive with rapid speed reversal and regenerative braking. A simple variable-structure current controller improves the system stability and robustness in performance. System large-signal operation and optimization are briefly discussed. Experimental results verify system development and design
