Özet: The paper introduces different control design methods for nonlinear systems with their application to the nonlinear mathematical model of a 3 DOF helicopter. Recent studies on the control design approaches, such as State Dependent Riccati Equation based optimal controller, Model Reference Adaptive Control and Sliding Mode Control, are reviewed and design methodologies are given. Then the mathematical model of a 3 DOF helicopter dynamics is derived and simplified with the software called CIFER. By using the simplified mathematical model of the 3 DOF helicopter, the control algorithms are applied to the model in order to explore the performances of the controllers. The results are given in the simulation environment. The paper is presented in a tutorial manner in order to explain the applications of the proposed nonlinear control methodologies.
