A robust high-speed sliding mode control of permanent magnet synchronous motor based on simplified hysteresis current comparison

A robust high-speed sliding mode control (SMC) of three phase permanent magnet synchronous motor (PMSM) is presented. The SMC served for inner speed while a simplified hysteresis current (HCC) scheme was used in the outer to generate gating signals inverter switches. present research leverages on ability directly access system error which it attempts driving zero by cancelling modelling uncertainties and disturbances. Performance comparison done model an existing having classical PI controller. With initial positive command 200 rpm at 5 Nm constant loading, rotor with neatly settled reference 0.085 seconds without overshoot controller 0.217 after overshoot. This translates 155.3% enhancement. Similar superior performance also observed during recovering from sudden reversal. While recovered -200 0.369 seconds, 0.482 seconds. From results, can be seen that demonstared superiority over conventioanl complex drives systems.
