数字解耦控制器设计及其在DDC上的实现

Design For Digital Decoupling Controller in DDC

介绍了一种通过设计数字解耦控制器来实现解耦的方法。该方法的优势在于它是通过软件的方式来实现解耦,无须增加任何硬件,在大大地节约了成本的同时也提高控制系统的稳定性能。数字解耦控制器在实际系统中的应用表明该方法取得了良好的控制效果。论文在介绍了目前常用四种解耦方法的基础上对数字解耦控制器的设计思想进行了论述,进而详细地介绍了数字解耦控制器的设计步骤,给出了数字解耦控制器的算法流程图。

This paper introduces a decoupling method by using a digital decoupling controller.The advantage of this me-thod is that it dose not need to add any device.Only using a software,the coupling can de eliminated.By this way we can both reduce the cost and improve the stability of the control system,The application of the digital decoupl-ing controller in a real system show that the method we used can get a good effect,This paper introduces four kinds of useful decoupling method and the idea of designing digital decoupling controller.Then it describes the process of designing a digital decoupling controller in detail and shows the arithmetic flow-chart of it.
