On the study of an optimal and robust control of the inverted pendulum wind turbine

Abstract

The main limitation of the optimal control is the requirement of complete system knowledge, this leads to the high sensitivity to parametric uncertainties and exogenous perturbations. A possible solution to this problem is to introduce a sliding mode control (SMC), well known for its robustness to uncertainties and disturbances, into optimal control whenever the uncertainties are present. This can make optimal control more robust and applicable to real energy systems. Though SMC and optimal control are two control strategies, it is possible integrate them together. In this work, combining (SMC) and linear quadratic regulator (LQR) will be analyzed, designed and applied to the new kind of wind turbine model, the so-called Inverted Pendulum Wind Turbine (IPWT). This new approach would allow to place offshore wind farms in deep water. All simulations are done using Matlab/Simulink.
