Abstract

The speed tracking and load disturbance regulation are contradictory elements, Two-degree-freedom(2 DOF) Internal Model Control (IMC) method is applied to solve the contradiction, but the 2 DOF is only used in a single output control system now. This paper presents the structure of 2 DOF-IMC for multiple output adjusting speed drive system of Synchronous Machine(SM), The controllers of air-gap-flux and rotor speed are proposed, based on 2 DOF-IMC principle. The characteristics of 2 DOF 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 and speed controllers based on 2 DOF-IMC, the proposed controllers provide very good dynamic response performances.
