查询词典 complex number

Aiming at a class of complex electromechanical systems, such as 4-high or multi-high cold mills and continual mills, we firstly construct mathematical models of every subsystems by means of structural principle modeling method; nextly, get the overall mathematical model of electromechanical drive system by joining together these subsystems'models according to coupling variables and parameters; we finally simplify the overall model according to time-scale principle which can retain main eigenvalues and significant state variables, and obtain a practical mathematical model of complex electromechanical system. By simulating the CM04 temper mill's model constructed by above-mentioned method, we test and verify that the modeling method is effective and practical. The study analyzes and researches the electromechanical coupling facts and acting laws existing in complex electromechanical system.
