PID CONTROL SYSTEM FOR A VARIABLE SPEED HORIZONTAL AXIS WIND MILL

In this work, a control system is designed for a horizontal axis wind turbine (HAWT). The suggested control system includes a conventional PID controller of a closed loop feedback. The nonlinear and linear models have been established for the turbine blades. Open loop Simulation was conducted using MATLAB/Simulink software, and results showed a considerable match to the actual system. A closed loop system was conducted and PID controller gains were tuned considering desired system performance characteristics until final gains were simulated in closed loop form which showed a considerable systems performance improving. Experimental results were analyzed and showed system stability and performance can be established.
