The generating systems use Doubly-Fed Induction Generators (DFIGs) to achieve high
conversion efficiency and to reduce the installation cost. This paper presents a modeling and Maximum
Power Point Tracking (MPPT) control method of DFIG-based variable-speed wind energy conversion
system. The generator considered is a wound rotor induction machine whose stator is connected directly
to the grid and the rotor is fed through back-to-back Pulse-Width Modulation (PWM) converters. Stator
flux-oriented vector control is applied to control the active and reactive current loops independently. The
MPPT control method in a Wind Energy Conversion System (WECS) is proposed. The proposed control
solution aims at driving the position of the operating point near to optimality. This is a very important
aspect to maintain DFIGs efficiently in a variable wind speed. The wind generator is modeled in RSCAD
program which is interfaced with the Real Time Digital Simulator (RTDS).

FIR_Filter
A 10th order FIR system, excited by a sum of 5 sinusoids. Assume any numeric
values for system coefficients and input signal parameters. The output of the system is
corrupted by Gaussian observation noise with zero mean and variance 2
σ v (consider 2
σ v = 0.1
and 1). The estimator has access to the input and noise corrupted output of the system.
However, the estimator has no knowledge about the system order, its coefficient values and
observation noise variance.
