A method of multiobjective synthesis of nonlinear robust electromechanical servo systems with parametric uncertainty is developed. Matrices of the nonlinear feedbacks regulator and the nonlinear observer are determined on the basis of the Hamilton-Jacobi-Bellman-Isaacs equations solutions. The goal vector of robust control is determined on the basis of the vector nonlinear programming problem solution, the vector objective function components are the direct quality indicators that are presented to the system in different modes of operation. The results of modeling and experimental research of the dynamic characteristics of a synthesized nonlinear electromechanical servo system are presented. References 10.
Key words: nonlinear robust electromechanical servo system, multiobjective synthesis, dynamic characteristics.
