Sequential multiobjective parametrical optimization of controllers for nonlinear control system

The technique of sequential (step-by-step) multiobjective parametrical optimization of controllers for nonlinear control systems are presented, which uses scalar optimization with integral and additive criteria on initial stages and sounding dynamic performances of a system on final stage with vector criteria. The example is given to Pareto-optimal tuning of digital PID-controller parameters for a nonlinear stabilization system.
