In this chapter, we show how the backstepping control design approach can be used to develop adaptive controllers for wind energy conversion systems (WECS). The focus is made on a WECS constituted of doubly fed induction generator (DFIG) and an AC/DC/AC converters association. The presented control strategy results in a multi-loop, nonlinear controller which is conceived to meet two control objectives: (i) speed reference optimization, in order to extract maximum wind energy despite the uncertainty and variations wind speed, and mechanical parameters; (ii) Power Factor Correction (PFC) to avoid net harmonic pollution. The entire nonlinear model is presented in the d-q framework and then based upon to design the multi-loop nonlinear controller using the adaptive backstepping design technique. A formal Lyapunov stability analysis is performed to prove the achievement of the control objectives. This theoretical result is confirmed by simulation with the MATLAB / Simulink software considering a 1.5 kW DFIG wind energy production system. The results of the simulation show that all control objectives (induction generator speed monitoring, stator flux, DC link voltage, and unit power factor control) are asymptotically achieved. |
