Abstract: Some formulations and computer-aided technologies for multiobjective parameter optimization of digital stabilization and tracking control systems with electromechanical plants are proposed, taking into account nonlinearities and disturbances in different dynamical modes. The practical examples are given to multiobjective parameter tuning of typical digital controllers.

Keywords: automatic control systems, digital controllers, multiobjective parameter optimization, direct sounding, pareto-solutions, nonlinearities, disturbances.
