Abstract :Variable speed turbo-generator control systems are consıdered as challenging issues for engineers. Some of these issues are type of machines to be used, location assessment, pitch angle control and maximum power extraction.  Almost all of these issues are facing a common problem which is changing in wind speed affects power delivered to the network. There is a novel idea in active 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 for variable speed turbo-wind generator. In order to consider adaptability of the method, final coefficients of the control system were considered to be weighted and stability is shown in simulation results. The back-stepping method allows for the design of adaptive control with the return process, and it can simultaneously regulate the stability of the closed loop system at the same time as design the control law. The addition of uncertainties to the problem in the form of specific coefficients due to the present of uncertainties due to the electrical and mechanical parameters. In the following, the designed method is simulated in MATLAB and SIMULINK. Simulation results show favorability and effectiveness of the proposed method.
