Fuzzy logic field oriented control of double star induction motor drive

Speed control of doubly star induction motor (DSIM) using direct field oriented control (DFOC) based on fuzzy logic controller (FLC)

“…The block diagram of the fuzzy logic for the DFOC approach of the DSIM is shown in figure 4. shows that responses for DFOC of DSIM using the proposed PI and FLC, We note that when the motor starts, the speed reaches its reference speed (100 rad/s), the mechanical torque increases to reach the peak value (44 N.m) and falls down to be close zero value because the motor running with no load. At during [2][3][4][5] sec we changed the value of load torque to Cr=10N.m, the motor output torque will increase to cover this load. The harmonics magnitude of electromagnetic torque produced by the FLC is inferior than produced by PI, Figure.6 (b).and the change in command speed is realized as following: ([0-6] sec ωr * =100rad/s) and (]6-9] sec ωr * =30rad/s).…”

“…The present study is focused on the doubly star Induction motor. This type of machine is composed by two three-phase windings shifted by 30 degrees and a standard simple squirrelcage rotor [2].…”

“…In order to ensure an effective control of DSIM, several methods have been proposed [3]. An alternative solution is the use of Direct Rotor-Field-Oriented Control (DFOC) is modern technique for high-performance control of PWM inverter fed DSIM.…”

Direct torque control of doubly star induction machine fed by voltage source inverter using type-2 fuzzy logic speed controller

“…The doubly star induction machine is demanded in aerospace applications and electric/hybrid vehicles, cement mills, rolling mills, mine hoists … etc (Zhao, 1995, Tir, 2016. Because this machine offers various advantages over conventional three-phase machines, such as minimize the amplitude and increasing the frequency of torque pulsation, minimize the current per phase, increasing the voltage per phase, reducing the rotor harmonic currents, and high reliability [1].…”

Adaptive Field-Oriented Control Using Supervisory Type-2 Fuzzy Control for Dual Star Induction Machine

“…Dual star induction machines (DSIM) have been used in many industrial applications due to their performances in high power fields and for highpower applications such as electric hybrid vehicles, locomotive traction and electric ship propulsion [1][2][3][4][5], and has many advantages, not only does give reduced torque pulsation, reduced rotor harmonics as they can be filtered and power segmentation but it also requires less powerful electronic components as the current flowing in a six-phase machine is less than that flowing in a three-phase machine [4] [6][7][8][9].…”
