random step function meaning in English
随机阶函数
Examples
- Abstract : the most critical task in designing a model based on predictive controller is identifying a reasonably good process model . the identification model of mould level of a continuous casting line in a steel plant is very difficult . due to the extremely high stochastic disturbance level , well - known parametric identification methods using random step function , prbs or stochastic test inputs are not successful . the present method based on orthogonal test inputs gives satisfactory results
文摘:在设计一种基于预测控制器模型时，最关键的工作是识别一个合理可靠的过程模型.在钢铁厂的连续铸造线上识别铸模液位模型是很困难的，由于极高的随机干扰水平，使得众所周知的随机阶跃函数， prbs或随机试验输入等参数识别方法都以失败告终.而本文介绍的基于正交检测的方法给出了令人满意的结果
