Sliding mode power tracking control based on hyperbolic tangent function of doubly fed induction generator Abstract: This article designs a sliding mode controller based on hyperbolic tangent function (SMC-tanh) to power direct control for a doubly fed induction generator (DFIG). The DFIG is an electrical asynchronous three-phase machine with open rotor windings which can be fed by external voltages and widely used in high power fields. The proposed controller was designed to ensure that the actual powers of the DFIG follow the desired powers in a finite time. The hyperbolic function was used to reduce the chattering phenomenon around the sliding surface. The stability of the system was proven by Lyapunov's theory. Simulation results in MATLAB/Simulink showed the effectiveness of the proposed controller without the overshoot, the steady-state converges to 0, the rising time, the settling time of the active and reactive power was 0.002(s), 0.0031(s) and 0.002(s), 0.0036(s), respectively. Keywords: Sliding mode control, Hyperbolic tangent function, Chattering, Power, Doubly fed induction generator. |
