Popis
Shrnutí:The method of accuracy improving and uncertain plant parameters sensitivity reducing based on multiobjective synthesis of two degree offreedom nonlinear robust control by discrete-continuous plant is developed. Synthesis of nonlinear robust regulators and nonlinear robust observers reduces to Hamilton-Jacobi-Isaacs equations solution. The robust control target vector is choiced by multicriterion nonlinear programming problem solution in which the objective function vectors is direct indexes performance vector that are presented to the system in various modes of its operation. The robust control target vector calculated by synthesized nonlinear robust control system modeling for various modes of system operation with different input signals and for various plant parameters values. The dynamic characteristics modeling end experimental researching results of a synthesized nonlinear electromechanical servo system for system operation various modes with different input signals and for plant parameters various values are given.
