Abstract

This paper shows the position regulation system problem of Synchronous Reluctance Motor(SRM) subject to parameter uncertainties and external disturbances. A novel fractional second-order nonsingular terminal Multisegment sliding mode control (F2NTMSMC) is proposed and the finite time stability of the closed-loop system is ensured. For the estimation and feedforward compensation for the lumped disturbances of SRM, a multisegment sliding mode disturbance observer is developed (MSMDO). The combined control scheme of F2NTMSMC and MSMDO can not only improve performance of the system but also reduce the chattering problem quickly. Developed simulation Results show that proposed control method is strongly robustness and also attain satisfactory position tracking performance as well as deal with the various uncertainty of the system.
