本文提出不需要辨识对象的多变量控制器的设计方法。假定开环对象是稳定的,而且对于阶跃输入,它的响应是基本不振荡的。对于这样的对象,不需要数学模型就能得到多变量的 I,PI 或 PID 控制器。本文还提出和论证了整定控制器的方法,首先以一个低阶线性蒸馏塔模型,而后以一个用于核电站的仿真研究的高阶非线性直流锅炉模型来加以说明。 This paper presents a design method of multivariable controller that does not require identification of objects. The open-loop object is assumed to be stable, and its response is essentially non-oscillating for step inputs. For such an object, a multivariable I, PI, or PID controller can be obtained without a mathematical model. This paper also presents and demonstrates the method of tuning the controller. First, a low-order linear distillation column model is used, and then a high-order nonlinear DC boiler model for nuclear power plant simulation is described.
