Research on the Multi-domain Servo-system

Multi-domain modeling and simulation has become increasingly widespread in practical demand.The object-oriented physical modeling language Modelica makes the multi-domain modeling relatively simple,and it could be simulated in the platform of Dymola which fully supports the Modelica language.Modeling and simulation of open servo-system and half-close servo-system is implemented in Modelica language under Dymola environment.Simulation results showed that multi-domain servo-system' dynamic performance was fine and identical to the practical analysis.Based on the openness of Modelica language,some relative models was created on the studied object' demand;Meanwhile,the library became more complete.Modelica/Dymola provides a way to investigate NC(Numerical Control) servo-system.
