| 摘 要： | 自抗扰控制是一种基于过程误差来减小误差的非线性鲁棒控制技术,适用于不确定性系统的控制.针对双级矩阵变换器(TSMC)系统的非线性强耦合特点,将自抗扰控制技术应用于TSMC的闭环控制中,建立了dq坐标系上TSMC的数学模型.根据模型的耦合、不确定性,引入自抗扰控制器,对系统内外扰进行观测和补偿.文中分析了自抗扰控制器ADRC各环节的功能原理、设计方法及参数整定规律.仿真结果表明,基于ADRC的闭环控制可保证TSMC系统在各种扰动下具有良好的动静态性能,验证了该控制策略的优越性.

| Abstract: | ADRC(auto-disturbance rejection controller) is a nonlinear-robust controller which reduces the errors based on process errors.It's fit for control of uncertainty systems.Refering to the non-linearity and strong coupling characteristics of two-stage matrix converter(TSMC),ADRC is applied in the closed-loop control of TSMC to observe and compensate the internal and external disturbances according to the coupling and uncertainties of TSMC,which is a mathematical model built in d-q rotating coordinate.The princ... |
