Hardware-in-the-loop based comparative analysis of speed controllers for a two-mass system using an induction motor drive with ideal stator current performance

A comparative study of speed control performance an induction motor drive system connecting to a load via non-rigid shaft. The nonrigidity the coupling is represented by stiffness and damping coefficients deteriorating regulating operations can be regarded as two-mass system. In paper, ability flatness based backstepping controls in verified through comprehensive hardware-in-the-loop experiments with assumption ideal stator current loop performance. Step-by-step design procedures are given, addition, responses classical PID also provided for parallel comparisons.
