A Design of CCIM Speed-Regulating Drive System Using Inverse Nyquist Array Method

本文应用多变量控制系统的逆Nyquist阵列频域设计法,对可控电流源型逆变器供电的感应电机(CCIM)调速传动系统进行设计.通过设计简单的解耦补偿器,使系统传递函数矩阵成为对角优势,以传感应电机定子电流和转速近似解耦.对电机转速和定子电流控制环按单回路独立设计,选择合适的控制器参数和反馈系数,使控制系统达到稳定且满足一定的性能指标.

This paper first proposes and describes the design of a Controlled Curr-ent Induction Motor(CCIM)speed-regulating drive system by using the InverseNyquist Array Method.By designing the suitable decoupling compensator,the system transfer function matrix can be become diagonal dominance andthe stator current and speed of motor can be decoupled approximately.So asystem with suitable feedback parameters and controller parameters,whichmake the system stable and satisfy certain performance index,can be selectedand designed simply and independently h serve as a single loop system.Thecomputer digital simulation and experiment results verified that the perfor-mance of the designed system is good.
