Nonlinear adaptive sliding mode based direct torque control of three phase induction motor speed control system [articol]

Abstract

Enlistment motor is a steady speed machine when worked from the mains. Anyway it is important to fluctuate the speed of the motor in a few applications. The speed of a motor essentially relies upon the supply frequency and number of shafts. The Field Programmable Gate Array (FPGA) innovation gives Programmable System-on-Chip (PSoC) situations for outlining modern computerized ASIC controllers for particular applications. This work introduces an FPGA based speed control Integrated Chip (IC) for three-phase induction motor drives. Direct torque control (DTC) is one technique utilized in factor frequency drives to control the torque of three-phase AC electric motors. This includes figuring a measurement of the motor's attractive flux and torque in view of the deliberate voltage and current of the motor. In this work was significantly reduce the torque flux and ripples based on Nonlinear Adaptive Sliding Mode controller with DTC scheme. The tuning of PID controller parameters to be used as a piece of a three-phase induction motor, NASMC system is utilized to tune each parameter of PID to improve the response of three phase induction motor drive structure. The Simulated results shows that the effectiveness of proposed NASMC controller and the simulation developed using Matlab Simulink software. A hardware model additionally created to approve the proposed simulation, in hardware FPGA based NASMC controller fed three phase Induction Motor is proposed utilizing single chip IC to work variable voltage and variable frequency, and in general 97% effectiveness was accomplished in full load condition.
