Simulation and hardware implementation of a sensorless modified MPTC for 3φ induction motor drives

Abstract

Model predictive torque control (MPTC) is developing as a high-performance control system for 3φ induction motor (IM) drives due to its simple structure and fast dynamic response. This paper proposes a sensorless modified MPTC (MMPTC) strategy to control the speed of 3φ IM drives. The suggested scheme uses an improved model reference adaptive system (MRAS) to estimate the rotor speed, motor fluxes, and improvement of the prediction model of the controller. Many experimental and simulation results using DSP/TMS320F28335 controller board and Matlab software are presented to validate the proposed control method. In addition, a comparative study for the traditional sensorless MPTC and proposed MMPTC is experimentally investigated. The presented results show low speed, torque, and flux ripples of the suggested MMPTC system at low-and high-speed ranges.
