【摘要】 工程设计方法设计的调节器难以兼顾调速系统的跟随性能和抗扰性能,采用二自由度内模控制可解决此问题,但目前二自由度内模控制主要应用于单变量的调速系统。本文基于二自由度内模控制原理,提出了多输出变量的同步电动机变频调速系统的二自由度内模控制结构,设计了二自由度磁链和转速内模控制器,进行了系统性能的计算机仿真。理论分析和仿真实验表明:在同步电动机变频调速系统的磁链和转速环采用二自由度内模控制,可各自独立地调节系统的跟随性能和抗扰性能,使系统获得优良的动态控制效果。更多还原

【Abstract】 The speed tracking and load disturbance regulation are contradictory elements,Two-degree-freedom(2DOF) Internal Model Control(IMC) method is applied to solve the contradiction,but the 2DOF is only used in a single output control system now.This paper presents the structure of 2DOF-IMC for multiple output adjusting speed drive system of Synchronous Machine(SM) ,The controllers of air-gap-flux&rotor speed are proposed,based on 2DOF-IMC principle.The characteristics of 2DOF have been verified by computer simulation.Theoretical analysis and simulation results show that the output tracking and outer disturbance regulation characteristics of SM are regulated respectively by using air-gap-flux flux& speed controllers based on 2DOF-IMC,the proposed controllers provide very good dynamic response performances.更多还原
