Synthesis and Multiobjective Optimization of Nonlinear Quasi Time–Optimal Digital Controllers

System Analysis and Control

In this paper some formulations of synthesis and multiobjective parameter optimization problems of digital servo systems with quasi time-optimal controllers are discussed and computer-aided techniques based on searching the Pareto-solutions are proposed. A practical example is given to demonstrate the multiobjective parameter tuning of nonlinear digital controller for servo system with linear plant.
