Control strategy for switched reluctance motor based on embedded system

Abstract

Mechatronics systems are are complex interdisciplinary products where many parts are present that overlap each other; electronic control board, electromechanical machines, and power drives. With FPGAs, their control can run faster as multiple operations are executed in parallel. A simulation tool that facilitates the direct translation into hardware of mechatronic control algorithms is desirable. The Xilinx System Generator (XSG), a high level tool for designing high-performance DSP systems under Simulink. In this paper such tool is exercised to implement a control mechanism for speed control of switched reluctance motor (SRM) with torque ripple reduction employing a heuristic approach of ant colony algorithm. The control scheme consists of proportional-integral (PI) speed controller in the outer loop and hysteresis controller in the inner loop along with control of turn on and turn off angles for the 3 phase, 6/4 switched reluctance motor. The efficiency of proposed technique is evaluated through simulative results that show proposed approach's performances in terms of ripples, stator current harmonics waves and short time design.
