This paper proposes a Takagi-Sugeno neuro-fuzzy inference system for direct torque and stator reactive power control applied to a doubly fed induction motor. The control variables (d-axis and q-axis rotor voltages) are determined through a control system composed by a neuro-fuzzy inference system and a first order Takagi-Sugeno fuzzy logic controller. Experimental results are presented to valid...

In this paper, an experimental study of a Wind Energy Conversion System (WECS) is performed. A test bench with power 1.5 kW setup. The system consists Doubly-Fed Induction Generator (DFIG) and wind emulator based on DC motor associated Maximum Power Point Tracking (MPPT) control. proposed driven by four quadrants DC/DC converter to produce real turbine behavior. aim work improve the DIFG perfor...

A new indirect stator flux field-oriented output feedback control for Doubly Fed Induction Machine is presented. It assures global exponential torque tracking and stabilization of the stator-side power factor at unity level, provided that electric machine physical constraints are satisfied. Based on the inner torque control system, a speed tracking controller, with load torque compensation is d...

With the rapid increase in proportion of installed wind power capacity total grid capacity, state has put forward higher and requirements for integration into grid, among which most difficult requirement is zero-voltage ride through (ZVRT) capability turbine. When voltage drops deeply, a series transient processes, such as serious overvoltage, overcurrent, or speed rise, will occur motor, serio...

Proportional Integral Derivative (PID) is the most popular controller used in automatic systems, because of its robustness, ability to adapt behaviors system, making them converge toward optimum. These advantages are valid only case linear as they present poor robustness nonlinear systems. For that reason, many solutions adopted improve PID The optimization algorithm presents an efficient solut...

Doubly fed induction generator (DFIG) wind power generation system is widely used in farm all over the world. Reactive can be generated both grid-side converter and generator-side of DFIG. In this paper, working principle control method DFIG are introduced, reactive limit derived, finally regulation simulated Simulink.

In this paper, a new control scheme is presented for the doubly-fed induction machine with specific applications to renewable energy (wind farms in particular). The proposed control algorithm offers the advantages of proven stability and remarkable simplicity. In contrast with the classical vector control method, where the doubly-fed induction machine is represented in a statorflux oriented fra...
