直流位置伺服系统的二自由度分数阶控制
Two-degrees-of-freedom Fractional Control Method for DC Position Servo System
摘要
Abstract
To improve the control performance in DC-position servo systems,we propose a two-degrees-of-freedom (2DOF)fractional-order control method.By designing a 2DOF control structure,we achieve decoupling con-trol of the system′s set-point tracking and disturbance rejection responses.Then,we develop a design method for the set-point tracking and disturbance rejection controllers by choosing a fractional-order filter by combi-ning internal model control (IMC)and fractional control.Based on the control performance requirements,we use the system′s cut-off frequency and maximum sensitivity index to analytically tune the parameters of the 2DOF controller.Simulation and experimental results show that the fractional-order 2DOF controller has good set-point tracking characteristics and disturbance rejection capability.关键词
