Dynamic Analysis of Turbo-Wind Generators and Real-Time Control Using Weighted Adaptive Method Considering Uncertainties

Abstract

Variable speed turbo-generator control systems are consıdered as challenging issues forengineers. Some of these issues are type of machines to be used, location assessment, pitch anglecontrol and maximum power extraction. Almost all of these issues are facing a common problemwhich is changing in wind speed affects power delivered to the network. There is a novel idea inactive control of wind turbine which has been developed to obtain maximum utilization of energy.In this study, adaptive BACK-STEPPING control laws were designed and implemented forvariable speed turbo-wind generator. In order to consider adaptability of the method, finalcoefficients of the control system were considered to be weighted and stability is shown insimulation results. The back-stepping method allows for the design of adaptive control with thereturn process, and it can simultaneously regulate the stability of the closed loop system at thesame time as design the control law. The addition of uncertainties to the problem in the form ofspecific coefficients due to the present of uncertainties due to the electrical and mechanicalparameters. In the following, the designed method is simulated in MATLAB and SIMULINK.Simulation results show favorability and effectiveness of the proposed method.
