| The paper investigates the application of numerical optimization methods for selecting controller parameters by using nonlinear quality criteria and taking into account non-linear equations of the object. A two-level procedure is proposed. At the internal level, a modal or LQR controller is constructed using a linearized model with quadratic or modal criteria parameters selected by the numerical method. This method is used at the external level to solve the controller optimization problem using additional nonlinear objective and constraint functions. The study has been performed on a specific example of controlling a nonlinear object. |
